The highest common factor (H.C.F) of the numbers 12, 16, and 18 is 2. To find the H.C.F, we can list the factors of each number: the factors of 12 are 1, 2, 3, 4, 6, 12; the factors of 16 are 1, 2, 4, 8, 16; and the factors of 18 are 1, 2, 3, 6, 9, 18. The largest factor common to all three sets is 2.
The hcf is 12
The HCF is 4. 16/4 is 4, 12/4 is 3
4
The GCF is 6.
The GCF is 2.
Since 12 is a factor of 24, it is automatically the GCF.
the hcf of 12 and 20 = 4
HCF of 12 and 18 is 6 and LCM of 108 and 72 is 216 So: 6 times 216 = 1296
The GCF is 6.
To find the HCF of 12 and 16, you first express them as the product of their prime factors: 12 = 2x2x3 16 = 2x2x2x2 The next step is to identify any common prime factors. In this case both numbers have two 2s as prime factors. Multiply these together and you get 4. Therefore the HCF of 12 and 16 is 4.
The GCF is 2.
The GCF is 6.
