8 and 12
4 and any multiple of 4 have a GCF of 4.
4 would be the GCF of those three numbers.
The GCF of all the composite numbers under 100 is 1. For e.g 4 & 9 are composite numbers & their GCF is 1, so if we take other composite numbers along with 4 & 9 the GCF will be 1.
(4,8) and (8,12) both have a GCF of 4.
No. The GCF of 4 and 8 is 4.
The GCF is 1.
To find a GCF, you need at least two numbers.
The GCF of the given two numbers is 4
5
You need at least two numbers to find a GCF.
The GCF of those numbers is 4. If 20 disappeared, the GCF of the remaining numbers would be 8.
the GCF of 4 3 5 is 1
