HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 814, 607, 838, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 814, 607, 838, 781 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 814, 607, 838, 781 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 814, 607, 838, 781 is 1.

HCF(814, 607, 838, 781) = 1

Highest common factor (HCF) of 814, 607, 838, 781 is 1.

Highest Common Factor of 814,607,838,781 using Euclid's algorithm

Highest Common Factor of 814,607,838,781 is 1

Step 1: Since 814 > 607, we apply the division lemma to 814 and 607, to get

814 = 607 x 1 + 207

Step 2: Since the reminder 607 ≠ 0, we apply division lemma to 207 and 607, to get

607 = 207 x 2 + 193

Step 3: We consider the new divisor 207 and the new remainder 193, and apply the division lemma to get

207 = 193 x 1 + 14

We consider the new divisor 193 and the new remainder 14,and apply the division lemma to get

193 = 14 x 13 + 11

We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get

14 = 11 x 1 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 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 814 and 607 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(193,14) = HCF(207,193) = HCF(607,207) = HCF(814,607) .

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

Step 1: Since 838 > 1, we apply the division lemma to 838 and 1, to get

838 = 1 x 838 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 838 is 1

Notice that 1 = HCF(838,1) .

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

Step 1: Since 781 > 1, we apply the division lemma to 781 and 1, to get

781 = 1 x 781 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 781 is 1

Notice that 1 = HCF(781,1) .
