∙ 11y agoUsing the prime factors of 14 and 6, the LCM is 42 (2 x 3 x 7).
The prime factorization of 42 is 2 x 3 x 7 Therefore the ascending sequence of numbers who could have a LCM of 42 is 2, 3, 6, 7, 14, 21 Pick the two which add to 20 6 + 14
It is: 18
Not always, sometimes the LCM equals the greatest number, i.e.the LCM of 5 and 6 is 30, the LCM of 3 and 6 is 6.
When the numbers are co-prime, ie have no common factor. Simplest example is 2 & 3 whose LCM is 6
The LCM is 42.
LCM(6, 12, 14) = 84
The LCM of the given three numbers is 42
The LCM is: 18
The LCM is: 42
Using the prime factors of 14 and 6, the LCM is 42 (2 x 3 x 7).
You need at least two numbers for an LCM. If that's 3 and 6, the LCM is 6.

The LCM of all these numbers is 72. (LCM of 9, 6, 3 is 18.) (LCM of 18, 8, is 72.)
