Find the GCF x^10y^4 , x^8y^2 , x^9y^2

Math
x10y4 , x8y2 , x9y2
Since x10y4,x8y2,x9y2 contain both numbers and variables, there are two steps to find the GCF (HCF). Find GCF for the numeric part then find GCF for the variable part.
Steps to find the GCF for x10y4,x8y2,x9y2:
1. Find the GCF for the numerical part 1,1,1
2. Find the GCF for the variable part x10,y4,x8,y2,x9,y2
3. Multiply the values together
