Question

Given that HCF (156, 78) = 78, LCM (156, 78) is
(A) 156
(B) 78
(C) 156 x 78
(D) 156 x 2​

Answer 1

we know that

hcf×lcm=product of numbers

therefore

78 ×LCM=78×156

LCM=156.

therefore option A is correct.

Answer 2

Option A. 156 is the LCM of the numbers.

Step-by-step explanation:

Given that HCF of 156 and 78 = 78

To find out LCM of 156 and 78 by two method.

(a) Integer numbers prime factorization : 2 × 2 × 3 × 13

    LCM = 156

(b) Let the LCM of 156 and 78 be L

Product of the numbers = 156 × 78

                                        = 12,168

Product of the numbers = HCF × LCM

12,168 = 78 × L

L = $\frac{12,168}{78}$

L = 156

Option A. 156 is the LCM of the numbers.
