Question

Find the $HCF$ and $LCM$ of the smallest prime number and smallest composite number?

Answer 1

The smallest prime number is $2$ and the smallest composite number is $4$

$\therefore$L.C.M$(2,4)=4$ since $4=2\times 2$ and $2=2\times 1$

H.C.F$(2,4)=2$ since $4=2\times 2$ and $2=2\times 1$ snd its common factor $2$
