WebThe Highest Common Factor (HCF) of two or more numbers is the greatest of all their common factors. Therefore, it is also called the greatest common factor (GCF). If we … WebAll the "2"s are now above each other, as are the "3"s etc. This allows us to match up the prime factors. The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12.. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of …
