By attacking them separately.

Example 30x2y3z4 and 42x4y5z2

Factor the coefficients.

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

For variables, just choose the highest number exponent.

The LCM of the above example is 210x4y5z4

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

You take each variable, in turn along with its highest power in any of the terms.

Thus LCM(x^2*y*z^3, x^4*y^2, y^2*z^2) = x^4*y^2*z^3.

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


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 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.


How do you find the LCM of 10a6c8 2a7c8 15a8c8?

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.
