he said that it would produce prime numbers for all integer values of m. This went on to to be true. What makes these number unique and beautiful, yet highly tricky, is that the primes become extremely big very fast, even within the limit of the first four iterations...
Recently someone suggested a similar technique for finding a big prime. The idea is to take the product of the first N primes and then add or subtract 1. Unfortunately this method doesn't work. While the new number is not divisible by the primes you use to build the number, there may ...
Given that f(3) = 2, f prime (3) = -1, g(3) = -3, g prime (3) = 8, A) Calculate (f + g) prime (3). B) Calculate (f - g) prime (3). C) Calculate (f * g) prime (3). D) Calculate (f/g) prime (3). Find the prime factorization of the following numbers. ...
But finding two numbers that are coprime isn't necessarily easy, especially if you're working it out by hand. In order to calculate a coprime, you have to first identify theprime factorsof a number, then you can use the result of this to find other numbers that are coprime to it. You...

It should be easy to see that phi(N) will be N - 1 whenever N is prime. Somewhat less obvious is the useful fact that phi(N) is also easy to calculate when N has exactly two different prime factors: phi(P * Q) = (P - 1) * (Q - 1), if P and Q are prime. ...
Assuming that p, q, and r are distinct primes, how many positive divisors does m have? 1) If {eq}m = q^3{/eq} 2) If {eq}m=p^2 q^2{/eq} 3) If {eq}m = pqr{/eq}Prime factorization:Each whole number has a unique prime factor...

we have to make a smallest prime factor for each no and store them now we create some hashset which contains the no of smallest prime factor divisor now we know that the no of pair of frequency of all the smallest individual prime no and we just calculate the all pair using some math...
