Consider the numbers 16 and 24.

A) 42
B) 44
C) 46
D) 48

Correct Answer:




D) 48

Description for Correct answer:
Factorisataion Method:

Factors of 16 are 2, 4, 8, 16

\( \Large \frac{16, 24}{2} = \frac{8, 12}{4} = 2, 3 \)

LCM of 16 and 24 is \( \Large 2 \times 4 \times 2 \times 3 = 48 \)

LCM = \( \Large \frac{Product\ of\ the\ given\ number}{HCF\ of\ the\ given\ number} \)
