WebThe GCF of 6 and 21 is 3. Steps to find GCF Find the prime factorization of 6 6 = 2 × 3 Find the prime factorization of 21 21 = 3 × 7 To find the GCF, multiply all the prime factors common to both numbers: Therefore, GCF = 3 MathStep (Works offline) Download our mobile app and learn how to find GCF of upto four numbers in your own time: WebWe consider the new divisor 6 and the new remainder 3, and apply the division lemma to get. 6 = 3 x 2 + 0. The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 36 and 21 is 3. Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(36,21) . Therefore, HCF of 36,21 using Euclid's division ...
LCM of 6 and 21 Methods to Find LCM of 6 and 21
WebThe final method for calculating the GCF of 6, 15, and 21 is to use Euclid's algorithm. This is a more complicated way of calculating the greatest common factor and is really only … WebExample 1: Two simple composite numbers. Calculate the highest common factor of 18 and 24. State the product of prime factors for each number, not in index form. 18 = 2 × 3 × 3. 24 = 2 × 2 × 2 × 3. 2 Write all the prime factors into the Venn diagram for each number. 3 Multiply the prime factors in the intersection to find the HCF. healthy meal bowl ideas
What is the greatest common factor of 6, 12 and 15?
Web6 = 3 x 2 + 0 The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 36 and 21 is 3 Notice that 3 = HCF(6,3) = HCF(15,6) … WebHighest Common Factor of 6,12 is 6. Step 1: Since 12 > 6, we apply the division lemma to 12 and 6, to get. 12 = 6 x 2 + 0. The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 … WebHCF of 9 and 21 is the largest possible number that divides 9 and 21 exactly without any remainder.
