WebSolution: ∵ LCM × HCF = 20 × 21. ⇒ HCF (20, 21) = (20 × 21)/420 = 1. Therefore, the highest common factor of 20 and 21 is 1. Example 3: Find the highest number that …
Greatest Common Factor (GCF, HCF, GCD) Calculator
WebNotice that 21 = HCF(42,21) = HCF(105,42) . We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma. Here 842 is greater than 21. Now, consider the largest number as 'a' from the given number ie., 842 and 21 satisfy Euclid's division lemma statement a = bq + r where 0 ≤ r < b . WebHCF (18, 42) = 6 HCF of 18 and 42 by Long Division Method The divisor we receive when the remainder is 0 after repeatedly doing a long division is the HCF of 18 and 42. No further division can be done. Hence, HCF (18, 42) = 6 HCF of … matt black paint for furniture
