What is the least common multiple for the pair of 16 and 24?

Answer 1

Well first of all, 24 is a multiple of 3, so only need to now calculate LCM of 16 & 24:

• 16 = 8 x 2
• 24 = 8 x 3

They share the common factor of 8, so the answer is 8 times the uncommon factors (2 x 3) or 8 x 2 x 3 = 48.

Answer 2

It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!

Answer 3

The LCM of 24 and 16 is 48.

The GCF/HCF of 24 and 16 is 8.

Answer 4

18 = 2*3*3 = 2*3^2 and 24 = 2*2*2*3 = 2^3*3. Therefore LCM = 2^3*3^2 = 8*9 = 72 and GCF = 2*3 = 6.

Answer 5

You need at least two numbers to find either of those.

Answer 6

2 and 48 respectively.

Answer 7

48
