The GCF is 3.
The GCF is 6.
the HCF is 6
HCF is the highest common factor of two or more numbers. HCF of 12 and 54 is 6.
It is 6

The Highest Common Factor (HCF) of 12 and 90 is 6. To find the HCF, you can list the factors of both numbers and identify the largest number that is common to both lists. The factors of 12 are 1, 2, 3, 4, 6, and 12, while the factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The largest number that appears in both lists is 6, making it the HCF.
Alright, buckle up, buttercup. The Highest Common Factor (HCF) of 10, 15, and 6 is 1. Why? Because the only number that can divide all three numbers without leaving a remainder is good ol' number 1. So, there you have it, the HCF is 1.
