Answer 2

HCF of 612 and 1314 is 18.

LCM of 612 and 1314 is 44676.

Step-by-step explanation:

Given : Numbers 612 and 1314.

To find : What is the HCF and LCM of numbers ?

Solution :

Factorizing the numbers,

$612=2\times2\times3\times3\times 17$

$1314=2\times3\times3\times73$

HCF is the highest common factor,

$HCF(612,1314)=2\times 3\times 3$

$HCF(612,1314)=18$

LCM is the least common multiple,

$LCM(612,1314)=2\times 2\times 3\times 3\times 17\times 73$

$LCM(612,1314)=44676$
