HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 729, 912, 951 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 729, 912, 951 is 3 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 729, 912, 951 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 729, 912, 951 is 3.
HCF(729, 912, 951) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 729, 912, 951 is 3.
Step 1: Since 912 > 729, we apply the division lemma to 912 and 729, to get
912 = 729 x 1 + 183
Step 2: Since the reminder 729 ≠ 0, we apply division lemma to 183 and 729, to get
729 = 183 x 3 + 180
Step 3: We consider the new divisor 183 and the new remainder 180, and apply the division lemma to get
183 = 180 x 1 + 3
We consider the new divisor 180 and the new remainder 3, and apply the division lemma to get
180 = 3 x 60 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 729 and 912 is 3
Notice that 3 = HCF(180,3) = HCF(183,180) = HCF(729,183) = HCF(912,729) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 951 > 3, we apply the division lemma to 951 and 3, to get
951 = 3 x 317 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 951 is 3
Notice that 3 = HCF(951,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 729, 912, 951?
Answer: HCF of 729, 912, 951 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 729, 912, 951 using Euclid's Algorithm?
Answer: For arbitrary numbers 729, 912, 951 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
