HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 401, 4779, 6931 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 401, 4779, 6931 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 401, 4779, 6931 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 401, 4779, 6931 is 1.

HCF(401, 4779, 6931) = 1

HCF of 401, 4779, 6931 using Euclid's algorithm

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

Highest common factor (HCF) of 401, 4779, 6931 is 1.

Highest Common Factor of 401,4779,6931 using Euclid's algorithm

Highest Common Factor of 401,4779,6931 is 1

Step 1: Since 4779 > 401, we apply the division lemma to 4779 and 401, to get

4779 = 401 x 11 + 368

Step 2: Since the reminder 401 ≠ 0, we apply division lemma to 368 and 401, to get

401 = 368 x 1 + 33

Step 3: We consider the new divisor 368 and the new remainder 33, and apply the division lemma to get

368 = 33 x 11 + 5

We consider the new divisor 33 and the new remainder 5,and apply the division lemma to get

33 = 5 x 6 + 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 401 and 4779 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(33,5) = HCF(368,33) = HCF(401,368) = HCF(4779,401) .

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

Step 1: Since 6931 > 1, we apply the division lemma to 6931 and 1, to get

6931 = 1 x 6931 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 6931 is 1

Notice that 1 = HCF(6931,1) .
