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
To find the HCF of two numbers you first have to split them into their prime factors: 45 = 3x3x5 36 = 2x2x3x3 The next step is to identify any common prime factors. In this example, both numbers have two 3s as prime factors. Multiply these together and you get: 3x3 = 9 Thus the hcf of 45 and 36 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 18.
