Best Answer

Example: 30 and 42

Factor them.

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Combine the factors, eliminating duplicates.

2 x 3 x 5 x 7 = 210, the LCM

You need at least two numbers to find an LCM.Two or more numbers are needed to find the Lcm

You write down the multiples of those four numbers and find the LCM. EX. 1:1,2,3,4,5,6,7,8,9,10,11,12 2:1,2 3:1,3 4:1,2,3 So the LCM is 2.

To find the LCM: 1. list out the factors of both numbers 2. find the one that is the least example 18: 1 2 3 6 9 18 16: 1 2 4 8 16 2 is the LCM

Find the LCM of the first two numbers and then find the LCM of that number and the third one. That answer will be the LCM of all three.

No. You can only find the LCM of at least two numbers, prime or otherwise. The LCM of any two prime numbers is their product.

First you Prime Factorize the two (or more) numbers. The LCM of the two (or more) numbers must contain all the prime factors of the two (or more) numbers that made it. To find the LOWEST common multiple, for each prime factor, find from one of the numbers where the prime factor has the highest power. The highest powers of each prime multiply together to form the LCM of the numbers. e.g. LCM of 36 and 24 36 = (2^2)(3^2) 24 = (2^3)3 LCM = (2^3)(3^2) = 72
