You need at least two numbers to find a GCF.
The GCF is 1.
The GCF is 1.
The GCF is 6.
The GCF is 9.
HCF(52, 35) = 1.
HCF(63, 45) = 9
It is: 7

HCF is the highest common factor of two or more numbers. HCF of 12 and 54 is 6.
The GCF/HCF of 54 and 504 is 18.
hcf(10, 21) = 1 ⇒ 10 & 21 relatively prime hcf(12, 54) = 6 ⇒ 12 & 54 not relatively prime hcf(15, 27) = 3 ⇒ 15 & 27 not relatively prime hcf(21, 38) = 1 ⇒ 21 & 38 relatively prime
