What is the lowest common multiple of 12 22 30?

Answer 1

To find the lowest common multiple of 3 numbers, you first need to break those numbers down into their prime factors. In this case, 12, 22 and 30 can be broken down as follows:

12 = 2x2x3

22 = 2x11

30 = 2x3x5

The next step is to identify any common factors. In this case, all three numbers have 2 as a factor, so we can discard 2 of these. Also, two numbers have 3 as a factor, so we can discard one of these. That leaves us with 2, 2, 3, 11 and 5. Multiply these together to find the LCM:

2x2x3x11x5 = 660.

Thus the lowest common multiple of 12, 22 and 30 is 660.
