# Find the GCF 40w^5 , w^2 , 14w^4 , w^7

40w5 , w2 , 14w4 , w7
Since 40w5,w2,14w4,w7 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 40w5,w2,14w4,w7:
1. Find the GCF for the numerical part 40,1,14,1
2. Find the GCF for the variable part w5,w2,w4,w7
3. Multiply the values together
