Question

Find the $\text{HCF}$ of $180,252$ and $354$ using prime factorization method.

Answer 1

Consider given numbers,

$\Rightarrow 180,252,354$

Now,

$180=2\times 2\times 3\times 3\times 5$

$252=2\times 2\times 3\times 3\times 7$

$354=2\times 3\times 59$

H.C.F of $180,252,354$ is _{=$2\times 3=6$}

Hence, this is the answer.
