The least common multipleof 7 and 9 is 63.
We're not sure what you mean by the lmm. Generally, people ask for the LCM (least common multiple) but to find that, you need at least two numbers to compare. The prime factorization of 42 is 2 x 3 x 7.
Without a specific value for A, we won't be able to come up with a specific LCM, no matter what method we use.
3 and 35
You need at least two numbers to find a GCF.
The Least Common Multiple of 8, 242 is 968.
The Least Common Multiple of 75, 105 is 525.
378
It is: 30
You need at least two numbers to find an LCM.
There is not a least common multiple of a single number, such as 130, because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common.
Least Common Multiple (LCM) for 8 42 is 168.
Least Common Multiple (LCM) for 27 48 is 432.
LCM of 288 and 39 is 3744
35 1*35 = 35 5*7 = 35
The Least Common Multiple (LCM) is the smallest number that two or more numbers will divide into evenly.
Suggestion: Find the least common multiple using your favorite method (for example, prime factorization). Then multiply that by 1, by 2, and by 3, to get your answer.
