**Definition of Prime Factor from Wikipedia:**In number theory, the prime factors of a positive integer are the prime numbers that divide that integer exactly. The process of finding these numbers is called integer factorization, or prime factorization.

**Example:**Prime factors of 288 are:

288 = 2 x 2 x 2 x 2 x 2 x 3 x 3

Here is a you tube video for you that will help you to understand prime factorization.

Now we are moving towards a C program that will find the prime factors of a number.

#### C Program to Find Prime Factors:

#include <stdio.h> int main() { int number,div; printf("Enter a number to know its prime factor: "); scanf("%d",&number); printf("\nThe prime factors of %d are: \n\n",number); div = 2; while(number!=0){ if(number%div!=0) div = div + 1; else { number = number / div; printf("%d ",div); if(number==1) break; } } return 0; }
