# Find the GCF mn^3 , m^4n , mn mn3 , m4n , mn
Since mn3,m4n,mn 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 mn3,m4n,mn:
1. Find the GCF for the numerical part 1,1,1
2. Find the GCF for the variable part m1,n3,m4,n1,m1,n1
3. Multiply the values together
Find the common factors for the numerical part:
1,1,1
The factors for 1 are 1.
The factors for 1 are all numbers between 1 and 1, which divide 1 evenly.
