For the greatest common factor, you check which variables appear in each of the expressions. In the case of exponents, you take the lowest exponent for each variable.
For the least common multiple, you take each variable, whether it appears in all of the expressions involved, or only in some of them. In the case of the exponents, you take the greatest exponent for each variable.
If there are numeric coefficients (numbers as products), you take either the gcf or the lcm of those in the usual way.
Example: 3x4y2 and 9x3y5 Treat the whole numbers normally. The LCM of 3 and 9 is 9. Choose the highest value of the variables. In this case, the LCM is 9x4y5
LCM(a2b5, a3b3) The LCM of both numbers HAS to have the largest coefficient of both variables. For a, it's a3, and for b it is b5. So the LCM is a3b5.
Two or more numbers are needed to find the LCM
You need at least two numbers to find an LCM.
You need at least two numbers to find an LCM.
Example: 3x4y2 and 9x3y5 Treat the whole numbers normally. The LCM of 3 and 9 is 9. Choose the highest value of the variables. In this case, the LCM is 9x4y5
Do the numbers first. The LCM of 6 and 8 is 24. Choose the higher of the variables. The LCM of 6a3 and 8a is 24a3
Example: 3x4y2 and 9x3y5 Treat the whole numbers normally. The LCM of 3 and 9 is 9. Choose the highest value of the variables. In this case, the LCM is 9x4y5

Two or more numbers are needed to find their 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.
The LCM is 189.

Choose the higher power. The LCM of x3 and x5 is x5
LCM(a2b5, a3b3) The LCM of both numbers HAS to have the largest coefficient of both variables. For a, it's a3, and for b it is b5. So the LCM is a3b5.
