The greatest common factor of 4a (2) b and 6ab (3)

4a^2b and 6ab^3

first, find the greatest common factor of ur coefficients 4 and 6 ... and that is gonna be 2

as for ur variables and exponents ... take the lowest ones

so both have an " a " and a " b " variable ... the lowest a term is just " a " ... and the lowest " b " term is b

so the GCF of these 2 terms are : 2ab
