Find the GCF xy^4 , xy^3 , xy

Math
xy4 , xy3 , xy
Since xy4,xy3,xy 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 xy4,xy3,xy:
1. Find the GCF for the numerical part 1,1,1
2. Find the GCF for the variable part x1,y4,x1,y3,x1,y1
3. Multiply the values together
Find the common factors for the numerical part:
