HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 517 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 811, 517 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, 517 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, 517 is 1.
HCF(811, 517) = 1
HCF of 811, 517 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, 517 is 1.
Highest Common Factor of 811,517 is 1
Step 1: Since 811 > 517, we apply the division lemma to 811 and 517, to get
811 = 517 x 1 + 294
Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 294 and 517, to get
517 = 294 x 1 + 223
Step 3: We consider the new divisor 294 and the new remainder 223, and apply the division lemma to get
294 = 223 x 1 + 71
We consider the new divisor 223 and the new remainder 71,and apply the division lemma to get
223 = 71 x 3 + 10
We consider the new divisor 71 and the new remainder 10,and apply the division lemma to get
71 = 10 x 7 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 811 and 517 is 1
Notice that 1 = HCF(10,1) = HCF(71,10) = HCF(223,71) = HCF(294,223) = HCF(517,294) = HCF(811,517) .
