A prime numbers is a number greater than one whose factors are only one and itself. In other words, 4 is not prime, because its factors are 1, 2 and 4 (1x4, 2x2). But 5 is prime, because the only way you can get a product of 5 is by multiplying 1 and 5 (1x5). Composite numbers are those who has more than two factors. The number 1 is not prime OR composite because it has only one factor.
Here are all the prime numbers up to 500:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, ...
How to find big Prime Numbers:
Following is a somewhat celebrated result of Euler:
The function f(x) = x^2 + x + 41 is always prime for x = 0, 1 ,..., 39.
This quadratic was the record holder for centuries as a consecutive,
Distinct quadratic prime-producer for an initial range of input
Values. It is not, however, the new function is there that can give more range of prime numbers than Euler’s:
The Function:
f(x) = 36x^2 - 810x + 2753
Which is always prime for x = 0, 1, ... , 44.

We would not be as strong as what we could have been. We could never fly!
A man found a cocoon of a butterfly. One day a small opening appeared. He sat and watched the butterfly for several hours as it struggled to force its body through that little hole. Then it seemed to stop making any progress. It appeared as if it had gotten as far as it could, and it could go no further. So the man decided to help the butterfly. He took a pair of scissors and snipped off the remaining bit of the cocoon. The butterfly then emerged easily. But it had a swollen body and small, shriveled wings. The man continued to watch the butterfly because he expected that, at any moment, the wings would enlarge and expand to be able to support the body, which would contract in time. Neither happened! In fact, the butterfly spent the rest of its life crawling around with a swollen body and shriveled wings. It never was able to fly. What the man, in his kindness and haste, did not understand was that the restricting cocoon and the struggle required for the butterfly to get through the tiny opening were God's way of forcing fluid from the body of the butterfly into its wings so that it would be ready for flight once it achieved its freedom from the cocoon. Sometimes struggles are exactly what we need in our lives. If God allowed us to go through our lives without any obstacles, it would cripple us. We would not be as strong as what we could have been. We could never fly!
I asked for Strength......... And God gave me Difficulties to make me strong.
I asked for Wisdom......... And God gave me Problems to solve.
I asked for Prosperity......... And God gave me Brain and Brawn to work.
I asked for Courage......... And God gave me Danger to overcome.
I asked for Love......... And God gave me Troubled people to help.
I asked for Favors......... And God gave me Opportunities.
I received nothing I wanted ........ I received everything I needed!
So don’t worry even if you mess up with your CAT paper, God is just making you strong to Fly......
CAT is finally OUT!
With limited access to CAT-related news in my hand, I thought the best way to help anyone interested in knowing about today's CAT test is to divert you to our mothership. Logon to www.careerlauncher.com for all the action.
All the best with the post-mortem :-)
Keep your cool!
I believe the most important virtue of the people who clear CAT is their ability to have a cool head. CAT is all about your ability to handle change and pressure.
I remember my high-pressure D-Day in 1996, when I was appearing for CAT. In the chilling December cold in Lucknow, when the temperatures go down to 5-8 deg C, it was an instant "hot" shock when we looked at the test paper. We were ready for a 4-section test with an open 2-hour period. Suddenly, we were told that we were supposed to do only English sections (Verbal and RC) in the first one hour, and then Quant+DI in the latter half. I, for one, was decided on spending only about 45 mins in English.
The change in CAT pattern inevitably results in lower cutoffs in the affected sections or the overall one. So I was pretty confident that I was not the only one who was in shock. The key was to get over the shock and come out a winner. So I did extremely well in the English with 15 mins extra. And since I expected the Math + DI cutoffs to be slightly lower, I did the right selection of questions, and maximized my scores there as well. I guess some people who were otherwise sharper than me, couldn't cope well with the pressure and got behind me. How else could I explain my IIM Seat when others, who were consistently better than me, couldn't!
I can relate to the situation better with a really motivating advertisement from Accenture. The inimitable Tiger Woods is shown trying to hit a ball stuck in deep pit with all his usual concentration. Many other players would have lost half of the game in this situation, but Tiger Woods' name is synonymous with Winning! The tag line puts it appropriately for the champion..."Conditions Change, Results Shouldn't".
So, while we start the countdown to CAT, don't forget that There Is But One Seat Reserved For You at the IIMs. You only have to make sure YOU get in it, NO MATTER WHAT!
