What is the LCM of 26 and 42?

Answer 1

To find the LCM of 26 and 42 you first need to break those numbers up into their prime factors. In this case, that would be:

26 = 2x13

42 = 2x3x7

The next step is to identify any common factors. In this case, both numbers have a 2 as a prime factor, so we can discard one of these. Take every other prime factor (2, 3, 7 and 13) and multiply them together to find the LCM:

2x3x7x13 = 546

Therefore the LCM of 26 and 42 is 546.
