HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 643, 8606, 8011 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 643, 8606, 8011 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 643, 8606, 8011 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 643, 8606, 8011 is 1.

HCF(643, 8606, 8011) = 1

Highest common factor (HCF) of 643, 8606, 8011 is 1.

Highest Common Factor of 643,8606,8011 using Euclid's algorithm

Highest Common Factor of 643,8606,8011 is 1

Step 1: Since 8606 > 643, we apply the division lemma to 8606 and 643, to get

8606 = 643 x 13 + 247

Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 247 and 643, to get

643 = 247 x 2 + 149

Step 3: We consider the new divisor 247 and the new remainder 149, and apply the division lemma to get

247 = 149 x 1 + 98

We consider the new divisor 149 and the new remainder 98,and apply the division lemma to get

149 = 98 x 1 + 51

We consider the new divisor 98 and the new remainder 51,and apply the division lemma to get

98 = 51 x 1 + 47

We consider the new divisor 51 and the new remainder 47,and apply the division lemma to get

51 = 47 x 1 + 4

We consider the new divisor 47 and the new remainder 4,and apply the division lemma to get

47 = 4 x 11 + 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 643 and 8606 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(47,4) = HCF(51,47) = HCF(98,51) = HCF(149,98) = HCF(247,149) = HCF(643,247) = HCF(8606,643) .


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

Step 1: Since 8011 > 1, we apply the division lemma to 8011 and 1, to get

8011 = 1 x 8011 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 8011 is 1

Notice that 1 = HCF(8011,1) .
