During a sale, color pencils were being sold in packs of $24$ each and crayons in packs of $32$ each. If you want full packs of both and the same number of pencils and crayons, how many of each would you need to buy?

Explanation:

We have to find the LCM of number of the color pencil in the box & number of crayons in each pack which is $24$ & $32$

$32=2\times 2\times 2\times 2\times 2;$

$24=2\times 2\times 2\times 3$

LCM$(32,24)=2\times 2\times 2\times 2\times 2\times 3=96$

In $1$ pack = $24$ pencils

$96$ pencils = $4\times 24$ = $4$packs

$32$ crayon = $1$ packs

$96$ crayon = $3\times 32$ crayons = $3$packs

Hence, we have to buy $4$ packs of pencils and $3$ pack of crayons.
