**Is 3 a prime factor?**

The first five prime numbers: 2, 3, 5, 7 and 11. A prime number is an integer, or whole number, that has only two factors — 1 and itself.

**What is the least prime factor of a +B?**

If 3 is the least prime factor of number a and 7 is the least prime factor of number b, then the least prime factor of a + b, is The least prime factor of a+b has to be 2; unless a +b is a prime number greater than 2.

## What is the least prime factor of two odd numbers?

Because both numbers are odd (otherwise 2 would be the least prime factor), this means that a + b is even.

## Can A+B be a prime number greater than 2?

Then the least prime factor of a is 2; which is not 3 or 7. So a can not be an even number nor can b be an even number. Hence a+b can not be a prime number greater than 2 if the least prime factor of a is 3 and b is 7. Thus the answer is 2.
