HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 461, 891, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 461, 891, 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 461, 891, 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 461, 891, 681 is 1.

HCF(461, 891, 681) = 1

HCF of 461, 891, 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 461, 891, 681 is 1.

Highest Common Factor of 461,891,681 using Euclid's algorithm

Highest Common Factor of 461,891,681 is 1

Step 1: Since 891 > 461, we apply the division lemma to 891 and 461, to get

891 = 461 x 1 + 430

Step 2: Since the reminder 461 ≠ 0, we apply division lemma to 430 and 461, to get

461 = 430 x 1 + 31

Step 3: We consider the new divisor 430 and the new remainder 31, and apply the division lemma to get

430 = 31 x 13 + 27

We consider the new divisor 31 and the new remainder 27,and apply the division lemma to get

31 = 27 x 1 + 4

We consider the new divisor 27 and the new remainder 4,and apply the division lemma to get

27 = 4 x 6 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 461 and 891 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(27,4) = HCF(31,27) = HCF(430,31) = HCF(461,430) = HCF(891,461) .

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) .
