The LCM of 248 and 868 is 1736. The HCF of the same two numbers is:

Correct option is A

Given:

LCM of 248 and 868 =1736

Solution:

HCF  of 248 and 868 

​$$248 = 2^3 \times 31 \\ 868 = 2^2 \times 7 \times 31 \\\text{Common prime factors: } 2^2 \times 31 \\\text{HCF} = 2^2 \times 31 = 4 \times 31 = 124$$​​
