WebSo, follow the step by step explanation & check the answer for HCF(15,21). Here 21 is greater than 15. Now, consider the largest number as 'a' from the given number ie., 21 and 15 satisfy Euclid's division lemma statement a = bq + r where 0 ≤ r < b . Step 1: Since 21 > 15, we apply the division lemma to 21 and 15, to get. 21 = 15 x 1 + 6 WebHCF of fractions = HCF of Numerators / LCM of Denominators Example: Let us take two fractions 4/9 and 6/21. 4 and 6 are the numerators & 9 and 12 are the denominators LCM (4, 6) = 12 HCF (4, 6) = 2 LCM (9, 21) = 63 HCF (9, 21) = 3 Now as per the formula, we can write: LCM (4/9, 6/21) = 12/3 = 4 HCF (4/9, 6/21) = 2/63 Property 4
