WebDetailed Answer: The Greatest Common Factor (GCF) for 18 and 63, notation CGF (18,63), is 9. Explanation: The factors of 18 are 1,2,3,6,9,18; The factors of 63 are 1,3,7,9,21,63. So, as we can see, the Greatest Common Factor or Divisor is 9, because it is the greatest number that divides evenly into all of them. Quote of the day... Web28 = 2 × 2 × 7. Find the prime factorization of 63. 63 = 3 × 3 × 7. To find the GCF, multiply all the prime factors common to both numbers: Therefore, GCF = 7. MathStep (Works …
HCF of 28, 63, 70, 72 using Euclid
WebStep 1: Apply Euclid’s division lemma, to a and b. So, we find whole numbers, q and r such that a = bq + r, 0 ≤ r < b. Step 2: If r = 0, b is the HCF of a and b. If r ≠ 0, apply the division lemma to b and r. Step 3: Continue the process until the remainder is zero. The divisor at this stage will be the required HCF of a and b. WebHCF of 27 and 63 by Long Division Method. In the division method, we divide the largest number by the smallest among the given numbers until the remainder is zero.
