The first thing you need to do to find the HCF is split each number into its prime factors.
9 = 3x3
36 = 3x3x4
Then you identify any shared factors. In this case, both numbers have two 3s, so those are our shared factors. Multiply these together for our answer:
3x3=9
Thus the HCF of 36 and 9 is 9.
The GCF is 9.
It is: 9
lcm(9, 12) = 36; hcf(9, 12) = 3.
The GCF is 9.
Their HCF is 1 and their LCM is 36
If you mean: 18, 27 and 36 then it is 9
The Highest Common Factor is 18
The HCF of both numbers is 9 and 9 times 9 = 81
16/36 = 4/9 by dividing the numerator and the denominator by 4 which is the HCF
The GCF is 4.
The GCF is 12.
The GCF is 18.
