HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 872, 3985, 9581 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 872, 3985, 9581 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 872, 3985, 9581 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 872, 3985, 9581 is 1.

HCF(872, 3985, 9581) = 1

HCF of 872, 3985, 9581 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 872, 3985, 9581 is 1.

Highest Common Factor of 872,3985,9581 using Euclid's algorithm

Highest Common Factor of 872,3985,9581 is 1

Step 1: Since 3985 > 872, we apply the division lemma to 3985 and 872, to get

3985 = 872 x 4 + 497

Step 2: Since the reminder 872 ≠ 0, we apply division lemma to 497 and 872, to get

872 = 497 x 1 + 375

Step 3: We consider the new divisor 497 and the new remainder 375, and apply the division lemma to get

497 = 375 x 1 + 122

We consider the new divisor 375 and the new remainder 122,and apply the division lemma to get

375 = 122 x 3 + 9

We consider the new divisor 122 and the new remainder 9,and apply the division lemma to get

122 = 9 x 13 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 872 and 3985 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(122,9) = HCF(375,122) = HCF(497,375) = HCF(872,497) = HCF(3985,872) .

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

Step 1: Since 9581 > 1, we apply the division lemma to 9581 and 1, to get

9581 = 1 x 9581 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 9581 is 1

Notice that 1 = HCF(9581,1) .
