Question

The LCM of two numbers is 6 times their HCF. The sum of the HCF and LCM is 210, then
HCF is equal to
(A) 1260
(B) 35
(C) 210
(D) 30​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

(D) 30

Step-by-step explanation:

Let the Numbers Are A and B

6 [ HCF(A,B) ] = LCM(A,B)

A + B = 210

HCF(A,B) + 6 [HCF(A,B)] = 210

7 [ HCF(A,B) ] = 210

HCF (A,B) = 30

So the Answer is (D) 30
