Question

Find the greatetime number that exactly divides 112

Answer 1

For a number k to exactly divide 112, there should exist another number m such that k*m = 112

For k to be large, m should be small

For m= 1 ; k=112 (this is obvious as every number is divisible by itself)

So, considering only proper divisors; for m = 2; k=56 is the greatest number that exactly divides 112
