HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 71, 627, 637 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 71, 627, 637 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 71, 627, 637 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 71, 627, 637 is 1.

HCF(71, 627, 637) = 1

HCF of 71, 627, 637 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 71, 627, 637 is 1.

Highest Common Factor of 71,627,637 using Euclid's algorithm

Highest Common Factor of 71,627,637 is 1

Step 1: Since 627 > 71, we apply the division lemma to 627 and 71, to get

627 = 71 x 8 + 59

Step 2: Since the reminder 71 ≠ 0, we apply division lemma to 59 and 71, to get

71 = 59 x 1 + 12

Step 3: We consider the new divisor 59 and the new remainder 12, and apply the division lemma to get

59 = 12 x 4 + 11

We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get

12 = 11 x 1 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 71 and 627 is 1

Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(59,12) = HCF(71,59) = HCF(627,71) .


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

Step 1: Since 637 > 1, we apply the division lemma to 637 and 1, to get

637 = 1 x 637 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 637 is 1

Notice that 1 = HCF(637,1) .
