We factorize the given numbers by using the prime numbers only.
Let we want to factorize the number 12

Now, 12 = 2 * 2 * 3
First, we star dividing the given number by the lowest prime number and then go up.
Any other numbers like 4, 6, etc are not allowed.
Again let another number 30

So, 30 = 2 * 3 * 5
In this way, we factorize the numbers.
