1. Find the GCF of 54a^2, 84ab and 10c 2. Find GCF of 14a^2b^4c and 56ab^2c^2.

Question

Help with GCF

54a^2,84ab and 10c.

14a^2b^4c and 56ab^2c^2

Answer 1

1. Find the GCF of

54a^2 = 2*3*3*3*a*a

84ab  = 2*2*3*7*a*b

10c  =2*5*c

2 is the only factor in all three numbers so that is the GCF.

 

2. Find GCF of

14a^2b^4c  = 2*7*a*a*b*b*b*b*c

56ab^2c^2 = 2*2*2*7*a*b*b*c*c

2*7*a*b*b*c is common or 14ab^2c
