HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 711, 759 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 637, 711, 759 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, 711, 759 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, 711, 759 is 1.

HCF(637, 711, 759) = 1

Highest common factor (HCF) of 637, 711, 759 is 1.

Highest Common Factor of 637,711,759 using Euclid's algorithm

Highest Common Factor of 637,711,759 is 1

Step 1: Since 711 > 637, we apply the division lemma to 711 and 637, to get

711 = 637 x 1 + 74

Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 74 and 637, to get

637 = 74 x 8 + 45

Step 3: We consider the new divisor 74 and the new remainder 45, and apply the division lemma to get

74 = 45 x 1 + 29

We consider the new divisor 45 and the new remainder 29,and apply the division lemma to get

45 = 29 x 1 + 16

We consider the new divisor 29 and the new remainder 16,and apply the division lemma to get

29 = 16 x 1 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 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 637 and 711 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(29,16) = HCF(45,29) = HCF(74,45) = HCF(637,74) = HCF(711,637) .

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

Step 1: Since 759 > 1, we apply the division lemma to 759 and 1, to get

759 = 1 x 759 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 759 is 1

Notice that 1 = HCF(759,1) .
