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
If you mean: 18, 27 and 36 then it is 9
They are 9 and 6
Well, honey, the highest common factor (HCF) of 9, 54, and 18 is 9. You see, 9 is the largest number that can divide all three numbers without leaving a remainder. So, there you have it - the sassy math answer you didn't know you needed.
The GCF is 18.
The GCF is 9.
9
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: 9
18
3
If that's 9 and 18, the GCF is 9.
factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2
Nine is HCF of 18 and 27
LCM=18=2*32 HCF(guess that is what u meant, highest common factor)=3 Possibilities: 3 and 18, 6 and 9, three or all of the numbers together. Note: 3 and 6 gives a LCM of 6 3 and 9 gives a LCM of 9 6 and 18 gives a HCF of 6 9 and 18 gives a HCF of 9 Three or four out of the numbers (3,6,9 and 18) will give you LCM of 18 and HCF of 3 as well.
If you mean: 18, 27 and 36 then it is 9
They are 9 and 6
