factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2
hcf(18, 30) = 6.
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
It is 6
HCF = 3... LCM = 18 !
The GCF is 3.
The GCF is 18.
The GCF is 9.
6 is the HCF of 18 & 48
The GCF is 6.
The HCF is 18
The hcf is 12
