Question

if 5 is the least prime factor of a number m and 11 is the least prime factor of a number n ,then the least prime factor of the number m+n is ?​

Answer 1

Answer:

Since, 3 is the least prime factor of 'a' therefore the number 'a' must be odd (because if the numbers would have been even then the least prime factor will definitely be 'z'.)

So, a is odd. similarly, b is also odd.

Hence a+b is even (than is, a multiple of 2)

Thus the least prime factor of 'a+b' is 2.
