The hcf of 12 & 36 is 12
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 hcf of 45 and 40 is 5.
HCF(36, 50) = 2LCM(36, 50) = 180
The hcf is 12
The GCF is 4.
The GCF is 4.
The GCF is 12.
