Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCM
least common multiple
the least common multiple, or LCM
least common multiple, or LCM.
Least common multiple is abbreviated as LCM.
The least common multiple of 45 and 25 is 225.The least common multiple of 25 , 45 = 225
The least common multipleof 7 and 9 is 63.
To find a common multiple - you need to have something to compare it to ! For example, the least common multiple of 2 & 3 is 6 !
To find the least common multiple, you need two terms. For example, the least common multiple of 120 and 5 would be 600 and the least common multiple of 120 and 16 would be 240. With one term, there is no least common multiple.
Since 63 is a multiple of 9, it is automatically the LCM of this problem.
The least common multiple of 3,4, and 60 is the same as the least common multiple of 12 and 60. This is because the least common multiple of 3 and 4 is 12. The answer to this problem is 60.
The least common multiple of 4 and 9 is 36.
That's known as the least common multiple, or LCM.
Since 289 is a multiple of 17, it is automatically the LCM of this problem.
Since 108 is a multiple of 4, it is automatically the LCM of this problem.
Since 12 is a multiple of 6, it is automatically the LCM of this problem.
Since 36 is a multiple of 9, it has to be the LCM of the problem.
Since 63 is a multiple of 3, it is automatically the LCM of this problem.
