Answer
$ 15,25,75$
$15=5 \times 3$
$25=5 \times 5$
$75=5 \times 5 \times 3 $
Product of the highest powers of the common factors $=3 \times 5^2$
$ =3 \times 25=75$
$\operatorname{LCM}(15,25,75)=75 $
$15=5 \times 3$
$25=5 \times 5$
$75=5 \times 5 \times 3 $
Product of the highest powers of the common factors $=3 \times 5^2$
$ =3 \times 25=75$
$\operatorname{LCM}(15,25,75)=75 $
