One per set of numbers.
It is: 15
The GCF is 9.
The GCF is 6.
5 and 10
The GCFs are 2, 1, 3, 1 and 1
Since numbers don't stop, GCFs don't either. To Infinity and beyond!
They aren't. 5 is the GCF of 35 and 75. It is the largest number that divides into both 35 and 75 evenly.
That's backwards. The GCF of 160 and 20 is 20.
2 and 4 are factors of 8. GCFs happen when you compare two or more numbers.
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.
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.
