The GCF is 4.
GCF of 36 and 45 is 9 36 = 9 x 4 45 = 9 x 5
The GCF of 4, 8 and 9 is 1.
The GCF of 4 and 9 is 1
The GCF of 4, 5, 8, and 9 is 1. Anytime the set for which you're trying to find the GCF includes at least one pair of consecutive integers, the GCF will be 1.
The GCF is 1.
9
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.
GCF(4, 7, 9) = 1.
4. 36/4 = 9 = 3 x 3 100/4 = 25 = 5 x 5
The GCF is 1.
