Question

Find HCF and LCM for $8,9$ and $25$

Answer 1

Factorizing $8,9$ and $25$, we get,

$8=2\times 2\times 2$

$9=3\times 3$

$25=5\times 5$

$\therefore$ HCF = $1$ [As $1$ is the only common factor of the given numbers.

LCM = $2\times 2\times 2\times 3\times 3\times 5\times 5$

$=8\times 9\times 25=1800$

Hence, HCF = $1$ and LCM = $1800$
