p and q are two positive integers such that the least prime factor of p is 3 and the least prime factor of q is 5 . Find the least prime factor of (p + q).

a and b are two positive integers such that the least prime factor of b is 3 and the least prime factor of b is 5. Then, the least prime factor of (a + b) is:

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

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
