What is the LCM of 12 22 and 30?
First, factor each number and express this way:12 = 22 x 322 = 2 x 1130 = 2 x 3 x 5Now, take the greatest power of each factor and find the product: 22 x 3 x 5 x 11= 660 is the LCMNote: I selected only the 22 because it was the greatest power of 2 than any other factor of "2" in the other numbers. I selected one 3 beause it was the greatest power of 3, and one 5 and one 11 because they were unique factors. This method will effectively find the LCM of any set of numbers.
What are the common factors of 660 and 770?
The common factors of 660 and 770 are: 1, 2, 5, 10, 11, 22, 55, and 110
What is the least common multiple of 15 and 44?
The least common multiple of 15 , 44 = 660
What is the LCM of 22 55 and 60?
Take the top two first.LCM is the product divided by the GCF55 factors to [5 11]60 factors to [2 2 3 5]common factor is 5, so LCM is 55 * 60 / 5 = 660Now, since 22 factors to [2 11] and both of them are in the above factors, 22 is a factor of 660 as well (22*30), so 660 is the answer. ■
