The first multiple is the LCM of 6, 7 and 8. Then you find LCM*2 and LCM*3.
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.

Find the LCM. That's one. Multiply it by 2 and 3.
Find their LCM and multiply it by 2 and 3.
How do you find the first three common multiples of sets of numbers
You can't have common multiples if they have nothing to be in common with however the first 3 multiples of 9 are 9,18 and 27 Think of just your times tables when finding out Multiples to find the first 5 multiples just count by 9's until you have said 5 numbers and Bingo
To find the answer, multiply whatever the number is by 1, 2 and 3.
Multiply 35 by the first three counting numbers. That will give you the first three multiples. To be common, they need to be compared to another set of multiples. If you meant 3 and 5, the LCM is 15. Multiplying 15 by 2 and 3 will give you the others.
Find the LCM. Multiply it by 2. Multiply it by 3.
you multiply them together
What is the process of finding the first three common multiples of 5 and 5
Multiply 11 by 18 and multiply that total by 2 and 3.
15 and 30 are common multiples of 3 and 5.
