Question

The HCF of two numbers is 13. Which one of the following can never be their LCM? ( A ) 60 ( B ) 156 ( C ) 91 ( D ) 39

Answer 1

"Option (A) 60" can never be their LCM.

Step-by-step explanation:

Given,

HCF of two numbers = 8.

This means 13 is a common  factor of both the numbers.

The LCM is the multiple of two numbers.

Check options:

( A ) 60 , it is not multiple of 13.

( B ) 156 = 12 × 13

( C ) 91 = 7 × 13

( D ) 39 = 3 × 13

Hence, option (A) 60 can never be their LCM.

Answer 2

Answer:

60

Step-by-step explanation:

60 is not the multiple of 13

13 × 12 = 156

13 × 7 = 91

13 × 3 = 39
