HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 681, 826, 305 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 681, 826, 305 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 681, 826, 305 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 681, 826, 305 is 1.

HCF(681, 826, 305) = 1

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

HCF of:

Highest common factor (HCF) of 681, 826, 305 is 1.

Highest Common Factor of 681,826,305 using Euclid's algorithm

Highest Common Factor of 681,826,305 is 1

Step 1: Since 826 > 681, we apply the division lemma to 826 and 681, to get

826 = 681 x 1 + 145

Step 2: Since the reminder 681 ≠ 0, we apply division lemma to 145 and 681, to get

681 = 145 x 4 + 101

Step 3: We consider the new divisor 145 and the new remainder 101, and apply the division lemma to get

145 = 101 x 1 + 44

We consider the new divisor 101 and the new remainder 44,and apply the division lemma to get

101 = 44 x 2 + 13

We consider the new divisor 44 and the new remainder 13,and apply the division lemma to get

44 = 13 x 3 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 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 681 and 826 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(44,13) = HCF(101,44) = HCF(145,101) = HCF(681,145) = HCF(826,681) .

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

Step 1: Since 305 > 1, we apply the division lemma to 305 and 1, to get

305 = 1 x 305 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 305 is 1

Notice that 1 = HCF(305,1) .
