1 and 5 are.
By an odd coincidence, those same numbers are
also the lowest common factors of 15, 10 and 20 .
Common factors of 15 and 18 are: 1 and 3.
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.
The Highest Common Factor (HCF) of 165 and 150 is 15. To find the HCF, you can list out the factors of each number and identify the highest common factor. The factors of 165 are 1, 3, 5, 15, 33, 55, and 165. The factors of 150 are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150. The highest common factor between the two numbers is 15.
