The GCF is 6.
If you mean: 18, 27 and 36 then it is 9
The GCF is 10.
HCF is the highest common factor of two or more numbers. One such pair which has 60 as their HCF can be: 120 and 180.
27
Nine is HCF of 18 and 27
The GCF is 6.
The GCF is 3.
The GCF is 6.
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
Any two numbers that have a common factor greater than 1 will have a LCM less than their product, eg: LCM(10, 15) = 30 < 10 x 15 = 150 (since HCF(10, 15) = 5) LCM(6, 10) = 30 < 6 x 10 = 60 (since HCF(6, 10) = 2) LCM(18, 27) = 54 < 18 x 27 = 486 (since HCF(18, 27) = 9)
The HCF of 12 and 60 is 12
If you are a teacher who works with 27 pupils and 18 pupils and
The GCF is 6.
The GCF is 20.
