HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 866, 863, 726 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 637, 866, 863, 726 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, 866, 863, 726 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, 866, 863, 726 is 1.

HCF(637, 866, 863, 726) = 1

Highest Common Factor of 637,866,863,726 using Euclid's algorithm

Highest Common Factor of 637,866,863,726 is 1

Step 1: Since 866 > 637, we apply the division lemma to 866 and 637, to get

866 = 637 x 1 + 229

Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 229 and 637, to get

637 = 229 x 2 + 179

Step 3: We consider the new divisor 229 and the new remainder 179, and apply the division lemma to get

229 = 179 x 1 + 50

We consider the new divisor 179 and the new remainder 50,and apply the division lemma to get

179 = 50 x 3 + 29

We consider the new divisor 50 and the new remainder 29,and apply the division lemma to get

50 = 29 x 1 + 21

We consider the new divisor 29 and the new remainder 21,and apply the division lemma to get

29 = 21 x 1 + 8

We consider the new divisor 21 and the new remainder 8,and apply the division lemma to get

21 = 8 x 2 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 866 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(29,21) = HCF(50,29) = HCF(179,50) = HCF(229,179) = HCF(637,229) = HCF(866,637) .


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

Step 1: Since 863 > 1, we apply the division lemma to 863 and 1, to get

863 = 1 x 863 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 863 is 1

Notice that 1 = HCF(863,1) .


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

Step 1: Since 726 > 1, we apply the division lemma to 726 and 1, to get

726 = 1 x 726 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 726 is 1

Notice that 1 = HCF(726,1) .
