WebThe HCF-Highest Common Factor of two numbers can be found by listing down all the factors and then selecting the highest common factor out of those. For example: Let's determine whether the given pairs of numbers are relatively prime or not a) 7 and 9; b) 8 and 10. a) 7 and 9 The factors of 7 are 1 and 7 The factors of 9 are 1, 3, and 9 WebThe highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one. For example, 8 and 12 have common factors of 1, 2 and 4. …
How to work out the HCF - Highest Common Factor - YouTube
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 60 … The simple steps to find the HCF of 4 numbers are: 1. First, divide the four numbers into pairs of two 2. Find the HCF of pair of two numbers 3. Then, find the HCF of HCFs calculated in the previous step 4.
