HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 727, 811, 905 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 727, 811, 905 is 1 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 727, 811, 905 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 727, 811, 905 is 1.
HCF(727, 811, 905) = 1
HCF of 727, 811, 905 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 727, 811, 905 is 1.
Highest Common Factor of 727,811,905 is 1
Step 1: Since 811 > 727, we apply the division lemma to 811 and 727, to get
811 = 727 x 1 + 84
Step 2: Since the reminder 727 ≠ 0, we apply division lemma to 84 and 727, to get
727 = 84 x 8 + 55
Step 3: We consider the new divisor 84 and the new remainder 55, and apply the division lemma to get
84 = 55 x 1 + 29
We consider the new divisor 55 and the new remainder 29,and apply the division lemma to get
55 = 29 x 1 + 26
We consider the new divisor 29 and the new remainder 26,and apply the division lemma to get
29 = 26 x 1 + 3
We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get
26 = 3 x 8 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 727 and 811 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(29,26) = HCF(55,29) = HCF(84,55) = HCF(727,84) = HCF(811,727) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 905 > 1, we apply the division lemma to 905 and 1, to get
905 = 1 x 905 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 905 is 1
Notice that 1 = HCF(905,1) .
