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.
LCM(26, 42) = 546.
The LCM of 26, 42, and 86 is 23,478
The LCM is 42.
The LCM is 42.
The least common multiple (LCM) of 21 and 42 is 42.
The LCM of 3 and 42 is 42.
