Question

Given that LCM (77, 99) =693, find the HCF (77,99)

Answer 1

product of two number = LCM ×HCF
77×99 = 693×HCF
So HCF = 77×99/693
= 11 ( Ans)

Answer 2

Step-by-step explanation:

HCF x LCM = Product of the the 2 no.s

Given LCM = 693

The 2 no.s are 77 and 99

HCF x 693 = 77 x 99

HCF x 693 = 7623

HCF = $\frac{7623}{693}$

HCF = 11
