HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 689, 641 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 581, 689, 641 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 581, 689, 641 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 581, 689, 641 is 1.

HCF(581, 689, 641) = 1

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

HCF of:

Highest common factor (HCF) of 581, 689, 641 is 1.

Highest Common Factor of 581,689,641 using Euclid's algorithm

Highest Common Factor of 581,689,641 is 1

Step 1: Since 689 > 581, we apply the division lemma to 689 and 581, to get

689 = 581 x 1 + 108

Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 108 and 581, to get

581 = 108 x 5 + 41

Step 3: We consider the new divisor 108 and the new remainder 41, and apply the division lemma to get

108 = 41 x 2 + 26

We consider the new divisor 41 and the new remainder 26,and apply the division lemma to get

41 = 26 x 1 + 15

We consider the new divisor 26 and the new remainder 15,and apply the division lemma to get

26 = 15 x 1 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 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 581 and 689 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(26,15) = HCF(41,26) = HCF(108,41) = HCF(581,108) = HCF(689,581) .

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

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

641 = 1 x 641 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 641 is 1

Notice that 1 = HCF(641,1) .
