HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 368, 711 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 637, 368, 711 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 637, 368, 711 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 637, 368, 711 is 1.

HCF(637, 368, 711) = 1

HCF of 637, 368, 711 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 637, 368, 711 is 1.

Highest Common Factor of 637,368,711 using Euclid's algorithm

Highest Common Factor of 637,368,711 is 1

Step 1: Since 637 > 368, we apply the division lemma to 637 and 368, to get

637 = 368 x 1 + 269

Step 2: Since the reminder 368 ≠ 0, we apply division lemma to 269 and 368, to get

368 = 269 x 1 + 99

Step 3: We consider the new divisor 269 and the new remainder 99, and apply the division lemma to get

269 = 99 x 2 + 71

We consider the new divisor 99 and the new remainder 71,and apply the division lemma to get

99 = 71 x 1 + 28

We consider the new divisor 71 and the new remainder 28,and apply the division lemma to get

71 = 28 x 2 + 15

We consider the new divisor 28 and the new remainder 15,and apply the division lemma to get

28 = 15 x 1 + 13

We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 637 and 368 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(71,28) = HCF(99,71) = HCF(269,99) = HCF(368,269) = HCF(637,368) .

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

Step 1: Since 711 > 1, we apply the division lemma to 711 and 1, to get

711 = 1 x 711 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 711 is 1

Notice that 1 = HCF(711,1) .
