What is a factor of 16 but not a multiple of 8?

### What number and 8 have the greatest common factor of 8 and the least common multiple of 24?

Both numbers must be multiples of 8, since their greatest common
factor is 8. The numbers cannot be larger than 24, since it is
their least common multiple. One of the numbers is 8. The only
other multiples of 8 that are equal to or less than 24 are 16 and
24. 8 and 16 have greatest common factor of 8 but least common
multiple of 16, so it cannot be this pair.
8 and 24 have greatest common factor of 8 and least common
multiple of 24, so this is the solution.

###### Asked in Math and Arithmetic

### Is 16 the least common multiple of 4 and 8?

The least common multiple of two numbers is the product of the
two numbers divided by their greatest common factor. The greatest
common factor of 4 and 8 is 8. (See related question "What is the
greatest common factor of 4 and 8?" for this calculation.) So, the
least common multiple is 4 x 8 ÷ 4 = 8.
Common multiples of 4 and 8 include 8, 16, 24, 32, 40, 48, 56,
64, 72, 80, etc. Although 16 is a common multiple, it is not the
least common multiple.

###### Asked in Math and Arithmetic, Factoring and Multiples

### The smallest common factor of 16 and 24?

There is no such thing as the smallest common factor. I guess
the smallest common factor (integers only) for 16 and 24 would be
-8. But that's just the negative version of the greatest common
factor. I think you meant to ask either what is the smallest common
multiple of 16 and 24 or what is the greatest common factor
of 16 and 24. The greatest common factor of 16 and 24 is 8. The
smallest common multiple of 16 and 24 is 48.
