12 = 2*2*316 = 2*2*2*2, with the common factors underlined.
So LCM = 2*2*2*3 = 24.
The LCM is 12.
The LCM is 144.
LCM of 8 and 12 is 24.
The LCM of 12 and 21 is 84. To find the LCM, prime factor both numbers then multiply each factor the most times it was used in either number.12=2x2x321=3x7lcm=2x2x3x7=84The Least Common Multiple (LCM) for 12 21 is 84.
You Do a Factor Tree which is very simple. But the answer is 12
The LCM is 12.
LCM(24, 60, 72) = 360.A common factor is 2.
To find the LCM of two or more numbers, you can list the multiples of each number:12, 24, 36...36, 72...In this case, we know that 36 there are no multiples of 36 less than 36 itself. We also can find quickly that 12 is a factor of 36, so 36 has to be the LCM of 12 and 36.
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
Use a factor tree to break apart numbers.ie. 12...../ \....2 6....../ \.....2 3The prime factors of 12 are 2, 2, and 3.
Since x is a factor of both numbers, ignore it and find the LCM of 7 & 12. These two numbers do not share any factors, so their LCM is 7*12 = 84. Put the x back in for the final answer - 84x.
The LCM is 300.
