Question

HCF of an even number and an odd number is an even number.

• A. True
• B. False

Answer 1

The correct option is B False

It is not necessary that H.C.F of an odd and even number is even.

For example : $6=2\times 3$ and $9=3\times 3$

It can bee seen clearly that H.C.F of $6$ and $9$ is $3$ which is odd.

Hence, It is not true that HCF of an even number and an odd number is an even number.
