∙ 11y ago
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

What is the LCM of the monomials 8y and 18y cubed?
72y
How do you find the gcf and LCM of numbers with variables and-exponents?
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.
How do you find LCM with variables with exponents?
1. Factor all possible parts 2. split the denominator 3. cross out 4. add like termms 5. simplify 6. done 7. math sucks
Lcm of 18 and 24 using prime factorization?
18 in pime exponents is 2*32 24 in prime exponents is 23*3 LCM: 23*32 = 72
What is the LCM of a2b5 plus a3b3?
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.
How do you find LCM with variables and exponents?

How do you find least common multipleand greatest common factor with a number that has variables and exponents next to it?
Do the numerical factors (coefficients) first. For the GCF of the variables, choose the lowest power of each. For the LCM of the variables, choose the highest power of each. Example 6x2y3z4 and 9x3y4z2 The GCF is 3x2y3z2 The LCM is 18x3y4z4
What is the LCM of the monomials 8y and 18y3?
72y^3

What do you do when you have a variable when trying to find the LCM?
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.
What is the LCM of the monomials 8y 18y to the power of 3?
72y^3
What is the LCM of the monomials 24a and 32a to the power of 4?
96a^4
How do you find the least common multiple with exponents?
You don't find an LCM with exponents. Exponents are just a shorter way to write it down after you find it. The LCM of 8 and 27 is 2 x 2 x 2 x 3 x 3 x 3. That can also be written as 23 x 33
How do you find LCM with variables with exponents?

When you have variables and your trying to find the LCM what would you do?
Choose the higher power. The LCM of x3 and x5 is x5
How do you find the LCM of 6a3 and 8a?
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
