Question
18 is divisible by both 2 and 3. It is also divisible by 2 × 3 = 6. Similarly, a number is divisible by both 4 and 6. Can we say that the number must also be divisible by 4 × 6 = 24? If not, give an example to justify your answer.
Solution
No. It is not necessary because 12 and 36 are divisible by 4 and 6 both, but are not divisible by 24.
