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.
The GCF of 16 and 72 is 8. 16/72 can be reduced to 2/9
The GCF is 100.
The GCF is 9.
The GCF is 1.
The GCF is 100.
The GCF is 9.
The GCF is 9.
The GCF is 9.
The GCF is 5.
4. 36/4 = 9 = 3 x 3 100/4 = 25 = 5 x 5
The GCF is 9.
