Using 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: 42
Using the prime factors of 14 and 6, the LCM is 42 (2 x 3 x 7).
The LCM is: 18
The LCM is: 42

You need at least two numbers for an LCM. If that's 3 and 6, the LCM is 6.
It is: 42
You need at least two numbers to find an LCM. If that's 6, 12 and 14, the LCM is 84.
The LCM of all these numbers is 72. (LCM of 9, 6, 3 is 18.) (LCM of 18, 8, is 72.)
