Question

if alpha and beta are 2 positive integers such that the least prime factor of A=3 and least prime factor of B=5.calculate the least prime factor of A+B

Answer 1

the least prime factor of A+B= 2

Answer 2

2

consider α,β since 3,5 are least prime factors.... both are odd
odd+odd=even
least prime of even is 2

hence least prime factor is 2
