Question

the product of two numbers is 2688. if their L.C.M is 336, find their H.C.F?

Answer 1

As we know,
Product of two numbers = Product of HCF and LCM of those two.
So, 2688 = HCF * 336
i.e. HCF = 2688/336 = 8.

Answer 2

HCF * LCM = product of two numbers
= 336 * HCF = 2688
= HCF = 2688/336
= HCF = 8
So,the HCF is 8.
Hope it helped.
