GCF of variables with exponents

The GCF is the common variable with smallest exponent.

example

9x4 - 27x6

the gcf is 9X4

because:

9x4 (1-3x2) = 9x4 - 27x6

In the same way:

X5 is the GCF of X10 + x5 -x6

Because X5 ( X5 + 1 -x1) = X10 + x5 -x6

Remember the exponent rule if you are multiplyin the same base, you keep the base and add the exponents

Hope this helps

Btw this does not help me!

How do you find GCF with varaibles only?

You look at the exponents. x5y2 and x3y4 The greatest common factor of these is the largest exponent of each. So the greatest common factor is: x3y2


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


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.

There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
