Question 5 • FL-1205010-M/J Grade 6 Mathematics A-CR

The least common multiple of two numbers is 24. Which could be the two numbers?

Answer
A
6 and 8
B
4 and 6
C
8 and 16
D
4 and 12

Explanation

The least common multiple is the smallest number that both numbers divide evenly. For 6 and 8, the first common multiple is 24: 6 × 4 = 24 and 8 × 3 = 24. The other pairs have least common multiples of 12, 16, and 12, respectively, so the pair that could have a least common multiple of 24 is 6 and 8.
