Well, honey, the Highest Common Factor (HCF) of 27 and 18 is 9. It's like finding the biggest number that can divide both 27 and 18 without leaving a remainder. So, there you have it, 9 is the winner in this mathematical showdown.
Nine is HCF of 18 and 27
It is: 3
The GCF is 3.
If you mean: 18, 27 and 36 then it is 9
Hint: divide num and denom by their HCF... 18/27 = 2/3
It means the highest common factor of two numbers or more. For example the HCF of 18 and 27 is 9 18=2×3×3 27=3×3×3 The common factor is 3×3=9
If you are a teacher who works with 27 pupils and 18 pupils and
27
It is: 27
27
HCF = 3... LCM = 18 !
The GCF is 3.
