HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 2034, 3922 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 641, 2034, 3922 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 641, 2034, 3922 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 641, 2034, 3922 is 1.

HCF(641, 2034, 3922) = 1

HCF of 641, 2034, 3922 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 641, 2034, 3922 is 1.

Highest Common Factor of 641,2034,3922 using Euclid's algorithm

Highest Common Factor of 641,2034,3922 is 1

Step 1: Since 2034 > 641, we apply the division lemma to 2034 and 641, to get

2034 = 641 x 3 + 111

Step 2: Since the reminder 641 ≠ 0, we apply division lemma to 111 and 641, to get

641 = 111 x 5 + 86

Step 3: We consider the new divisor 111 and the new remainder 86, and apply the division lemma to get

111 = 86 x 1 + 25

We consider the new divisor 86 and the new remainder 25,and apply the division lemma to get

86 = 25 x 3 + 11

We consider the new divisor 25 and the new remainder 11,and apply the division lemma to get

25 = 11 x 2 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 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 641 and 2034 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(25,11) = HCF(86,25) = HCF(111,86) = HCF(641,111) = HCF(2034,641) .

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

Step 1: Since 3922 > 1, we apply the division lemma to 3922 and 1, to get

3922 = 1 x 3922 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 3922 is 1

Notice that 1 = HCF(3922,1) .
