The LCM of a set of integers is the smallest positive integer which can be divided evenly by each number in the set. The LCM of the set is the same however it is calculated.

LCM- using 14 12 and 10 is 420

24 12,2 6,2,2 3,2,2,2 49 7,7 No common prime factors. The LCM is their product.

That's a lot of extra work for this problem but here goes. 3 is already prime so it doesn't really have a factor tree or prime factorization. The prime factorization of 4 is 2 x 2 which looks like this in a factor tree.42,23 and 4 have no common prime factors, so the LCM is their product, 12

it is a method in mathematics that helps to find out LCM

you have to use a factor tree

16080,240,2,220,2,2,2102,2,2,25,2,2,2,2,2You need another number to compare this one with to find a GCF or an LCM.

The LCM is: 12 to find the LCM you can make a factor tree of each number and after you did that you find a number that all the factor trees have in common and write that number once and if there is more than one number in common with all of the factor trees also write that number down once the rest of the numbers are extras so you want to write those done too then you multiply all the numbers written down and you get the LCM

The factor tree finds the prime factorization. The prime factorization finds the LCM. Example: 30 and 42 Factor them. 30 15,2 5,3,2 42 21,2 7,3,2 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 HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.

28 14,2 7,2,2 35 5,7 2 x 2 x 5 x 7 = 140, the LCM

32=2x16=2x2x8=2x2x2x4=2x2x2x2x2 45=3x15=3x3x5 LCM=(2x2x2x2x2)x(3x3x5) =1440

Since 360 is a multiple of 120, it is automatically the LCM.

70 35,2 7,5,2 98 49,2 7,7,2 2 x 5 x 7 x 7 = 490, the LCM

The LCM is: 50

The greatest common factor is 4. The LCM is 600.

If done correctly, yes.

2 x 25Combine the factors.2 x 2 x 5 = 20, the LCM

There is no common factor so the LCM is 3300

The LCM is 65.

LCM(24, 60, 72) = 360.A common factor is 2.

multiple

40 20,2 10,2,2 5,2,2,2 50 25,2 5,5,2 2 x 2 x 2 x 5 x 5 = 200, the LCM

"Lowest or Least Common Factor"LCM is basically the method, used to determine the factors of any specific number or value, the Factors will be smallest in value.just like LCM of "16" is "2x2x2x2"but it can also be done as 8x2 or 4x4.So the LCM is basically the Lowest value factor that you can find.Improved Answer:-LCM means the lowest common multiple of two or more numbers as for example the LCM of 3 and 4 is 12

3 2 x 3 x 7 = 42 Since 42 is a multiple of 3, it is automatically the LCM of the pair.
