$8, 12$
$8, 12$
✓
Answer
$ 8,12$
$8=2 \times 4=2 \times 2 \times 2$
$12=2 \times 6=2 \times 2 \times 3 $
Product of common factors $=2 \times 2=4$
Product of other factors $=2 \times 3=6$
LCM $=$ Product of common factors $\times$ Product of other factors
$=4 \times 6=24$
$\operatorname{LCM}(8,12)=24$.
$8=2 \times 4=2 \times 2 \times 2$
$12=2 \times 6=2 \times 2 \times 3 $
Product of common factors $=2 \times 2=4$
Product of other factors $=2 \times 3=6$
LCM $=$ Product of common factors $\times$ Product of other factors
$=4 \times 6=24$
$\operatorname{LCM}(8,12)=24$.
