To find the Least Common Multiple (LCM) of two or more numbers, write down the multiples of the numbers until they match. I will use 6 and 9 as an example.
6: 6, 12, 18...
9: 9, 18, 27...
The numbers in bold are your LCMs. 18 is the LCM of 6 and 9.
Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
Select the highest amount of each factor.
2 x 3 x 5 x 7 = 210, the LCM
Check it.
30 x 42 = 1260
210 x 6 = 1260
It checks.

Since they have no common prime factors, multiply them together.3 x 7 x 10 = 210, the LCM
This does not work when one of the numbers is negative.
12 is a factor of 24 so you need only consider the LCM of 20 and 24.20 = 4*5 24 = 4*6 So the LCM is 4*5*6 = 120.
Well ok here is the whole thingy 10: 20 5:5,10,15,20 LCM:20 You need to do the rest of the work
The LCM is: 10The LCM is 10.
To work out the LCM, you need two numbers. You have provided only one so you can't work out the LCM.
Do the numbers first. The LCM of 6 and 8 is 24. Choose the highest of the powers. The LCM is 24a^3
The LCM of 12 and 7 is their product which is 12 times 7 = 84
50 should work: 50 = 5 * 10 and 50 = 2* 25.
List the multiples.6, 12, 18, 249, 18, 27The LCM is 18.
The LCM of 2,3, and 5 is 30 since they are all primes we must find the LCM by multiplying them all together.
The LCM of 4 and 7 is 28 because...4x7=28 and anything under 28 wouldn't work
prime factorization of each: 2x3 , 3x5, 2x2x5 so LCM = 2x2x3x5 = 60
The least common multiple (LCM) of 48 and 72 is 144.
Here you go! https://en.wikipedia.org/wiki/Least_common_multiple
you have to use a factor tree
Since they have no common prime factors, multiply them together.3 x 7 x 10 = 210, the LCM
