25, 49 and 121
4 and 9 have a GCF of 1
12 & 16
12 and 16
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.
16, 32 and 48
10,20
4 and 9 have a GCF of 1
12 & 16
They could be 12 and 18
No need to answer it anymore.
They are all composite numbers whose GCF is 1
12 and 16
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 answer is 45 60 and 90
16, 32 and 48
15, 30, 45
7, 14 and 21
