What is the least common multiple of 14 10 45?

Answer 1

To find the least common multiple of numbers, you first need to split them into their prime factors:

14 = 2x7

10 = 2x5

45 = 3x3x5

The next step is to identify common factors. Two numbers have 2 as a factor so wee can discard one of these. Two numbers have 5 as a factor, so we can discard one of these also. This leaves us with 2, 7, 3, 3, 5. To find the LCM, you just multiply these numbers together:

2x7x3x3x5 = 630. Thus the least common multiple of 14, 10 and 45 is 630.
