The LCM will contain all factors including variables. Look at coefficients and find their LCM. Then IF several terms have a common factor with a differnt exponent, use that variable with the largest exponent. If a variable appears in only one term, it will still be part of the LCM with its exponent.

EX Find LCM for 14s3 and 6 ---- ANSWER --- 42s3

Ex Find Lcm for 3x2y , 4y3, and 7x --- The LCM is 84x2y3 biggest exponents even if not in all terms.

It very much depends on what variable you are trying to find and what information is available.

Most times the question will specify "find the HCF" or "find the LCM." If you're trying to find common denominators, that's an LCM problem. If you're trying to reduce fractions, that's an HCF problem.

Choose the higher power. The LCM of x3 and x5 is x5

Use the LCM for their coefficients.Use each vriable with the LARGEST exponent in each term.Ex: Find the LCM of 15 x2y5 and 20 x3y4LCM of 15 and 20 is 60, LCM of x2 and 20 x3 is x3 , LCM of y5 and y4 is y5So the LCM is 60 x3y5

A variable can be any number. The LCM possibilities are infinite.

The GCF is useful when you are trying to reduce fractions. The LCM is useful when you are trying to add and subtract unlike fractions.

1 can only be an LCM (least common multiple) if the numbers you're trying to find an LCM for are 1 and 1. LCM cannot be smaller than the largest of the numbers you're using.

It is called the independent variable. For example if you are trying to find y: y = x+1 X is the independent variable, and Y is the dependent variable. The value of Y, depends on the value of X.

The Independent Variable is the variable being manipulated. The dependent variable is what your trying to get a conclusion of.

A common question in mathematics asks you to find two pairs of numbers with a given LCM. It is trying to find out whether you know what an LCM is, how to find it and reinforces the fact that more than one pair of numbers can have the same LCM. Q. Find two pairs of numbers with the LCM of 36. A. 4 and 9, 12 and 18 (Other answers are possible.)
