a.
To find the Greatest common factor (GCF).
a.
Answer to Problem 4ST
The greatest common factor is
Explanation of Solution
Given: The integers is ,
Concept Used: Greatest common factor (GCF).
The Greatest common factor (GCF) of two or more integers is the greatest integer that is a factor of each.
Calculation: The Greatest common factor (GCF) is obtained as,
The GCF of
Compare the power of each variable occurring in both monominals. Use the power with the least exponent.
