Question

Find the $H.C.F$ and $L.C.M$ of $576,720$.

Answer 1

Factors of $576=2\times 2\times 2\times 2\times 2\times 2\times 3\times 3$

Factors of $720=2\times 2\times 2\times 2\times 3\times 3\times 5$

L.C.M$=2\times 2\times 2\times 2\times 2\times 2\times 3\times 3\times 5=2880$

H.C.F$=2\times 2\times 2\times 2\times 3\times 3=144$
