First you need to find the prime factors of 28 and 42.
28= 7x22
42= 7x3x2
Then you multiply 7x3x22, the product of which is 84, which is your answer.
The least common multiple of 64 and 96 is 192.
The Least Common Multiple (LCM) of (15,33,44) is 660.
least common multiple of 30 and 75 is 150.
The Least Common Multiple of 14, 20, and 22 is 1,540.
the common denominator!
The Least Common Multiple of 8, 242 is 968.
The Least Common Multiple of 75, 105 is 525.
Prime factorization of 15 = 3x5Prime factorization of 50 = 2x5x5Prime factorization of 75 = 3x5x5LCM = 5x5x3x2 = 150

72 is the least common multiple of 24 and 18. 72 = 3*3 * 2*2*2.
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.
It is: 30
The LCM of 7 and 15 is 105.The prime factorization of 7 = 7The prime factorization of 15 = 3 * 5The least common multiple is the product of the pair divided by their GCF, which is 1.= 3 * 5 * 7= 105Their product.
The LCM of 3, 5, and 12 is 60The factorization of 3=3The factorization of 5=5The factorization of 12=2x2x3LCM=2x2x3x5=60The least common multiple of 3 , 12 , 5 = 6060
You need at least two numbers to find an LCM.
Prime factorization helps to find the greatest common factor and the least common multiple which, in turn, help in the adding, subtracting and reducing of fractions.
Only if they're the same number.
