The GCF is 5.
The GCF of 45 and 80 is 5. Prime factors: 45 = 5x3x3 80 = 5x2x2x2x2 the only prime factor in both is 5, and so the highest common factor is 5. Alternative method: 80 mod 45 = 35 45 mod 35 = 10 35 mod 10 = 5 10 mod 5 = 0 so HCF = 5.
The GCF is 35.
The GCF is 7.

The GCF of 20 35 45 is 5.
The GCF is 1.
9 is not a factor of 35; therefore the answer is: does not exist.
greatest common factor of 45 and 35 is 5.Five (7*5 , 9*5)
The GCF is 5.
