You need at least two numbers to find a GCF.
The GCF is 15.
The GCF is 5.
9.Why? Because 9 x 6 = 54, and 9 x 5 = 45. No number larger than 9 is both a factor of 54 AND 45.
The HCF of 54 and 45 is 9
The GCF/HCF of 54 and 504 is 18.
The GCF is 18.
The hcf of 45 and 40 is 5.
The HCF is 18
HCF is the highest common factor of two or more numbers. HCF of 12 and 54 is 6.
The HCF is 1.
