To find the common multiples of two numbers, you first break them into their prime factors:
6 = 2x3
8 = 2x2x2
The next step is to identify any common prime factors. In this case both 6 and 8 have 2 as a common factor, so we can discard one 2. Then take every other prime factor (2, 2, 2 and 3) and multiply them:
2x2x2x3 = 24.
To find other common multiples you would multiply this lcm by any integer. In this case, we only want multiples less than 48, and so the only valid value is 24.
Multiples of 6 that are less than 72 are: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, and 66.
24 and 48
There are 6 multiples of 8 that are less than 50.
30, 36, 42, 48
The are: 42 48 54 60 and 66
36, 42, 48, 54, 60, and 66
6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66
They are: 6 12 18 24 30 36 42 and 48
12, 24, 36, 48.
Multiples of 6 that are less than 36 are: 6, 12, 18, 24, and 30.
These: 6, 12, 18, 24, 30, 36, 42, 48.
The 16 whole multiples of 6 that are less than 100 are: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96. There are an infinite number of multiples of 6, because there are an infinite number of whole numbers.
