Find their LCM and multiply it by 2 and 3.

15 and 30 are common multiples of 3 and 5.

The first thing you should notice is that both 8 and 12 are evenly divisible by 2. This means that any common multiples of 8 and 12 will also be multiples of 2. So we only really need to find the first three common multiples of 8 and 12.First common multiple: 248 * 3 = 2412 * 2 = 24(2 * 12 = 24)Second common multiple: 488 * 6 = 4812 * 4 = 48(2 * 24 = 48)Second common multiple: 728 * 9 = 7212 * 6 = 72(2 * 36 = 72)

To find common multiples you first need to split the numbers into their prime factors: 4=2x2 8=2x2x2 10=2x5 The next step is to cross off any duplicates. All numbers have one 2, so we can discard 2 of them. Two numbers have an additional 2, so we can discard one of them. This leaves us with 2,2,2 and 5. Multiply these together for the lowest common multiple: 2x2x2x5=40 To find other common multiples you simply times 40 by 2,3,4 and so on. So the first three common multiples of 4,8, and 10 are 40, 80 and 120.

To find common multiples you first need to break up the numbers into their prime factors. In this case: 4=2x2 9=3x3 12=2x2x3 The next step is to identify common factors and discard the duplicates. Two numbers have two 2s so we can discard two of these. Also, two numbers have a 3, so we can discard 1 of these. That leaves us with 2, 2, 3 and 3. Multiply these together for the LCM: 2x2x3x3 = 36 To find other multiples, you simply multiply the LCM by 1,2,3 etc. So the first three common multiples are 36, 72 and 108.
