You can't. You need at least two numbers to find a GCF.
Factor them.
2 x 2 x 2 x 5 = 40
2 x 5 x 7 = 70
Select the common factors.
2 x 5 = 10, the GCF
3 x 7 = 21
2 x 5 x 7 = 70
The GCF is 7.
2 x 2 x 2 x 5 = 40
2 x 5 x 7 = 70
The GCF is 8.
The GCF is 14.
The greatest common factor of 70 , 66 = 2
The greatest common factor of 32 , 70 = 2
The Greatest Common Factor of 70, 140, 175: 35
the highest common factor of 14 and 70 is: 14. hope this helped :)
The GCF is 14.
The GCF is 14.
thw greastest common factor of 10 50 and 70 is 10
The greatest common factor of 14, 28, and 70 is 14.
The highest common factor of 49 and 70 is 7
The greatest common factor of 26 and 70 is 2.
The greatest common factor of 70 , 66 = 2
The greatest common factor of 32 , 70 = 2
The GCF is 14.
The GCF (Greatest Common Factor) of 70 and 3542 is: 14
The Greatest Common Factor (GCF) of 70 and 148 is 2
The Greatest Common Factor of 30, 70: 10
