Question

If 3 is a least prime factor of a number a and 7 is the least prime factor of number b, Find the least 1 prime factor of (a+b).? with proper steps please

Answer 1

Answer:

least prime factor of "a" is 3 and least prime factor of "b" is 7

so sum of least prime factors of a and b = 3+7 = 10

and least factor of 10 is 2

so least factor of a + b is also 2
