HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 581, 37 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 811, 581, 37 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 811, 581, 37 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 811, 581, 37 is 1.
HCF(811, 581, 37) = 1
HCF of 811, 581, 37 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 811, 581, 37 is 1.
Highest Common Factor of 811,581,37 is 1
Step 1: Since 811 > 581, we apply the division lemma to 811 and 581, to get
811 = 581 x 1 + 230
Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 230 and 581, to get
581 = 230 x 2 + 121
Step 3: We consider the new divisor 230 and the new remainder 121, and apply the division lemma to get
230 = 121 x 1 + 109
We consider the new divisor 121 and the new remainder 109,and apply the division lemma to get
121 = 109 x 1 + 12
We consider the new divisor 109 and the new remainder 12,and apply the division lemma to get
109 = 12 x 9 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 811 and 581 is 1
Notice that 1 = HCF(12,1) = HCF(109,12) = HCF(121,109) = HCF(230,121) = HCF(581,230) = HCF(811,581) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 37 > 1, we apply the division lemma to 37 and 1, to get
37 = 1 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 37 is 1
Notice that 1 = HCF(37,1) .
