Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the highest amount of each factor.
2 x 3 x 5 x 7 = 210, the LCM
The Least Common Multiple of 75, 105 is 525.
The least common multiple of the numbers 4, 27 and 9 is 108.
You need at least two numbers to find a common multiple.
378
The least common multiple of 42 and 126 is 126.
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.
You need at least two numbers to find an LCM.
Prime factorization.
The LCM of these numbers is 740. LCM is Least Common Multiple.
If the prime factorizations have no factors in common, the LCM is the product of them.
The Least Common Multiple of 8, 242 is 968.
The Least Common Multiple of 75, 105 is 525.
The least common multiple of the numbers 2,357 and 11 is 25,927.The least common multiple of the numbers 23, 57 and 11 is 14,421.
All numbers with a least common multiple, have that multiple as a factor.
The least common multiple is one of the numbers when one of the numbers is a multiple of the other.
The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of each of the numbers in the set. For sets of multiples, the LCM is the smallest number that is a multiple of all the numbers in the sets. The LCM can be calculated by finding the prime factorization of each number and then taking the highest power of each prime factor that appears in any of the numbers.
The least common multiple of the numbers 12 and 34 is 204.
