What is the hcf of 18 32 48?

Answer 1

The GCF is 2.

Answer 2

To find the highest common factor (HCF) of 18, 32, and 48, you need to first find the prime factors of each number. The prime factors of 18 are 2 x 3^2, 32 can be broken down into 2^5, and 48 is 2^4 x 3. To find the HCF, you take the common prime factors with the lowest exponent, which in this case is 2^1 = 2. Therefore, the HCF of 18, 32, and 48 is 2.

Answer 3

HCF(18, 32, 48) = 2.
