MCQ
$\text{LCM}$ of $\left(2^3 \times 3 \times 5\right)$ and $\left(2^4 \times 5 \times 7\right)$ is :
- A$40$
- B$560$
- C$1120$
- ✓$1680$
✓
Answer
Correct option: D.
$1680$
$\left(2^3 \times 3 \times 5\right)$ and $\left(2^4 \times 5 \times 7\right)$
$\text{LCM } =2^4 \times 3 \times 5 \times 7=1680$
$\text{LCM } =2^4 \times 3 \times 5 \times 7=1680$
