The GCF is 18.
The GCF/HCF of 54 and 504 is 18.
It is: 18
The HCF is 18
hcf(18, 54, 81) = 9. Using prime factorization: 18 = 2 x 3^2 54 = 2 x 3^3 81 = 3^4 hcf = 3^2 = 9
The GCF is 9.
The greatest common factor of 54 and 90 is 18.
Factors of 26 - 1, 2, 13, 26 Factors of 54 - 1, 2, 3, 6, 9, 18, 27, 54 HCF = 2
18 and 36 do. So do 18 and 54, 36 and 54, 18 and 72, 54 and 72, and an infinite number of other pairs of numbers.
To find this, you first have to split the numbers into their prime factors: 18 = 2x3x3 54 = 2x3x3x3 The next step is to identify any common prime factors. In this case both numbers have a 2 and two 3s as prime factors. Multiply these together gives you: 2x3x3 = 18 Therefore the HCF of 18 and 54 is 18.
The GCF is 18.
The greatest common factor of the numbers 24 and 54 is 6.
