HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 817, 459, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 817, 459, 681 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 817, 459, 681 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 817, 459, 681 is 1.

HCF(817, 459, 681) = 1

HCF of 817, 459, 681 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 817, 459, 681 is 1.

Highest Common Factor of 817,459,681 using Euclid's algorithm

Highest Common Factor of 817,459,681 is 1

Step 1: Since 817 > 459, we apply the division lemma to 817 and 459, to get

817 = 459 x 1 + 358

Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 358 and 459, to get

459 = 358 x 1 + 101

Step 3: We consider the new divisor 358 and the new remainder 101, and apply the division lemma to get

358 = 101 x 3 + 55

We consider the new divisor 101 and the new remainder 55,and apply the division lemma to get

101 = 55 x 1 + 46

We consider the new divisor 55 and the new remainder 46,and apply the division lemma to get

55 = 46 x 1 + 9

We consider the new divisor 46 and the new remainder 9,and apply the division lemma to get

46 = 9 x 5 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 817 and 459 is 1

Notice that 1 = HCF(9,1) = HCF(46,9) = HCF(55,46) = HCF(101,55) = HCF(358,101) = HCF(459,358) = HCF(817,459) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 681 > 1, we apply the division lemma to 681 and 1, to get

681 = 1 x 681 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 681 is 1

Notice that 1 = HCF(681,1) .
