HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 806, 923, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 806, 923, 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 806, 923, 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 806, 923, 681 is 1.

HCF(806, 923, 681) = 1

HCF of 806, 923, 681 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 806, 923, 681 is 1.

Highest Common Factor of 806,923,681 using Euclid's algorithm

Highest Common Factor of 806,923,681 is 1

Step 1: Since 923 > 806, we apply the division lemma to 923 and 806, to get

923 = 806 x 1 + 117

Step 2: Since the reminder 806 ≠ 0, we apply division lemma to 117 and 806, to get

806 = 117 x 6 + 104

Step 3: We consider the new divisor 117 and the new remainder 104, and apply the division lemma to get

117 = 104 x 1 + 13

We consider the new divisor 104 and the new remainder 13, and apply the division lemma to get

104 = 13 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 806 and 923 is 13

Notice that 13 = HCF(104,13) = HCF(117,104) = HCF(806,117) = HCF(923,806) .

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

Step 1: Since 681 > 13, we apply the division lemma to 681 and 13, to get

681 = 13 x 52 + 5

Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 5 and 13, to get

13 = 5 x 2 + 3

Step 3: We consider the new divisor 5 and the new remainder 3, and apply the division lemma to get

5 = 3 x 1 + 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 13 and 681 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(681,13) .
