Q The LCM and HCF of two numbers are 196 and 20 respectively How
many such pair(s) of numbers can be possible?
(A) 0
(B) 1
(C) 2
(D) 3
(E) None of these

Dhruv Gupta · Answer

Dear student,

We know that

HCF X LCM = The product of 2 nos

So, LCM has to be a multiple of the HCF which will yield a
integer

But 196/20 = 9 8 which is not a integer

So, 0 pairs are possible

Therefore, the answer is at (A)

hope this helps
