One per set of numbers.
It is: 15
The GCF is 9.
5 and 10
The GCF is 6.
Since numbers don't stop, GCFs don't either. To Infinity and beyond!
The GCFs are 2, 1, 3, 1 and 1
2 and 4 are factors of 8. GCFs happen when you compare two or more numbers.
That's backwards. The GCF of 160 and 20 is 20.
You need at least two numbers to find a GCF. If that's 55 and 9, or 5 and 59, their GCFs are both 1.
They aren't. 5 is the GCF of 35 and 75. It is the largest number that divides into both 35 and 75 evenly.
I'll exchange them for the numbers you want to know the GCF of.
GCFs refer to integers. The GCF of 4, 18 and 24 is 2.
