WebHCF of 21, 49, 84 by Euclid's Divison lemma method can be determined easily by using our free online HCF using Euclid's Divison Lemma Calculator and get the result in a fraction of seconds ie., 7 the largest factor that exactly divides the numbers with r=0. Highest common factor (HCF) of 21, 49, 84 is 7. HCF(21, 49, 84) = 7 WebMar 29, 2024 · Step 1: The first step is to use the division lemma with 49 and 21 because 49 is greater than 21. 49 = 21 x 2 + 7. Step 2: Here, the reminder 21 is not 0, we must use … WebWrite each number as a product of its prime factors. 2 2 x 3 x 5 = 60. 3 x 5 2 = 75. The product of all common prime factors is the HCF. The common prime factors in this example are 3 & 5. The lowest power of 3 is 3 and 5 is 5. So, HCF = 3 x 5 = 15. Example 2: Find the HCF of 36, 24 and 12. how to save dying money tree
