Question

I need urgent help in maths
Find the L.C.M. of 140 and 168. Use the L.C.M. obtained to find the H.C.F.
of the given numbers.

Answer 1

Step-by-step explanation:

Numbers are 140 and 168

LCM of 140 and 168 = 840

We know that

Product of two numbers = Product of their H.C.F and L.C.M

HCF = 1st number ×2nd number / LCM

HCF = 140×168/ 840
