You need at least two numbers to find a GCF.
The GCF of 20, 35, and 70 is 5.
The GCF is 10.
The GCF is 10.
The GCF of 30 and 20 is 10. The GCF of 40 and 20 is 20.
The GCF is 5.
the GCF of 30, 50, and 70 is10
The GCF is 5.
10 and 210, respectively.
The greatest common factor (GCF) of 20 and 70 is 10.10
10 and 140, respectively.
The GCF is 10.
gcf(20, 30, 90) = 10
The GCF is 2.
The GCF is: 10
The GCF is 5.
Take your pick; 10 and 20, 10 and 30, 10 and 40, 10 and 50, 10 and 60, 10 and 70, 10 and 80, 10 and 90, 20 and 30, 20 and 50, 20 and 70, 20 and 90, 30 and 40, 30 and 50, 30 and 70, 30 and 80, 40 and 50, 40 and 70, 40 and 90, 50 and 60, 50 and 70, 50 and 80 50 and 90, 60 and 70, 70 and 80, 70 and 90, 80 and 90.
