What are the HCF of 15 and 20? - Answers
Web15 = 12 x 1 + 3. Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 3 and 12, to get. 12 = 3 x 4 + 0. The remainder has now become zero, so our procedure stops. Since … WebLet's find out the common factors of the given numbers: 8, 12, 15, and 18. Step 1: First of all we will find out the factors of the given numbers. Factors of 8 = 1, 2, 4, and 8. Factors of 12 = 1, 2, 3, 4, 6, and 12. Factors of 15 = 1, 3, 5, and 15. Factors of 18 = 1, 2, 3, 6, 9, and 18. nursing homes in orrville ohio
HCF of 10 and 15 How to Find HCF of 10, 15? - Cuemath
WebHCF of 12, 15 and 21 can be represented as HCF of (HCF of 12, 15) and 21. HCF (12, 15, 21) can be thus calculated by first finding HCF (12, 15) using long division and thereafter … HCF of 12 and 15 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly. 1. Step 1: Divide15 (larger number) by 12 (smaller number). 2. Step 2:Since the remainder ≠ 0, we will divide the divisor of step 1 (12) by the remainder (3). 3. Step 3:Repeat this process until the … See more Prime factorization of 12 and 15 is (2 × 2 × 3) and (3 × 5) respectively. As visible, 12 and 15 have only one common prime factor i.e. 3.
