## How do you find the prime factor of a number Program?

Following are the steps to find all prime factors.

1. 1) While n is divisible by 2, print 2 and divide n by 2.
2. 2) After step 1, n must be odd. Now start a loop from i = 3 to square root of n.
3. 3) If n is a prime number and is greater than 2, then n will not become 1 by above two steps. So print n if it is greater than 2.
