Question

find the hcf and lcm of 693, 1078

Answer 1

Answer:

The HCF and LCM are 77 and 9702 respectively

Step-by-step explanation:

Given two numbers  693, 1078

we have to find the HCF and LCM of above two numbers.

By prime factorization method

$693= 3\times 3\times 7\times 11$

$1078=2\times 7\times 7\times 11$

$HCF(693, 107)=7\times 11 =77$

$LCM(693, 107)=3\times 3\times 7\times 7\times 11\times 2=9702$

Hence, the HCF and LCM are 77 and 9702 respectively
