The GCF is 1.
The GCF of 18, 4 and 27 is 1. I saw this straight away as 4 only has factors of 4, 2 and 1. 4 or 2 don't go into 27. Therefore the GCF has to be 1.
The GCF of 16 and 72 is 8. 16/72 can be reduced to 2/9
The GCF is 4 16/36 = 4/9.
The GCF is 9.
The GCF is 9.
Factors of 4: 1, 2, 4 Factors of 9: 1, 3, 9 Factors of 16: 1, 2, 4, 8, 16 GCF (4, 9, 16) = 1
The GCF of 9, 27, and 45 is 9.
the greatest common factor for 45 and 27 is 9.
The factors of 32 are:1, 2, 4, 8, 16, 32The factors of 36 are:1, 2, 3, 4, 6, 9, 12, 18, 36The factors of 45 are:1, 3, 5, 9, 15, 45The Greatest Common Factor (GCF) is:1
The GCF is 9.
The GCF is 27.
GCF = 9
