HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 9138 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 811, 9138 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, 9138 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, 9138 is 1.
HCF(811, 9138) = 1
HCF of 811, 9138 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, 9138 is 1.
Highest Common Factor of 811,9138 is 1
Step 1: Since 9138 > 811, we apply the division lemma to 9138 and 811, to get
9138 = 811 x 11 + 217
Step 2: Since the reminder 811 ≠ 0, we apply division lemma to 217 and 811, to get
811 = 217 x 3 + 160
Step 3: We consider the new divisor 217 and the new remainder 160, and apply the division lemma to get
217 = 160 x 1 + 57
We consider the new divisor 160 and the new remainder 57,and apply the division lemma to get
160 = 57 x 2 + 46
We consider the new divisor 57 and the new remainder 46,and apply the division lemma to get
57 = 46 x 1 + 11
We consider the new divisor 46 and the new remainder 11,and apply the division lemma to get
46 = 11 x 4 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 811 and 9138 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(46,11) = HCF(57,46) = HCF(160,57) = HCF(217,160) = HCF(811,217) = HCF(9138,811) .
