Hcf of 21 and 15
WebRelated GCF Calculator Factor Calculator. What is a factor? A factor is a term in multiplication. For example, in: 3 × 4 = 12, 3 and 4 are the factors. It is possible for a number to have multiple factors. WebThe variable r varies according to 0 ≤ r ≤ b. We can use this to figure out the HCF of 21,15,12,208. This is how to do it. Step 1: The first step is to use the division lemma with 21 and 15 because 21 is greater than 15. 21 = 15 x 1 + 6. Step 2: Here, the reminder 15 is not 0, we must use division lemma to 6 and 15, to get. 15 = 6 x 2 + 3
