HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 693, 406 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 811, 693, 406 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 811, 693, 406 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 811, 693, 406 is 1.

HCF(811, 693, 406) = 1

Highest common factor (HCF) of 811, 693, 406 is 1.

Highest Common Factor of 811,693,406 using Euclid's algorithm

Highest Common Factor of 811,693,406 is 1

Step 1: Since 811 > 693, we apply the division lemma to 811 and 693, to get

811 = 693 x 1 + 118

Step 2: Since the reminder 693 ≠ 0, we apply division lemma to 118 and 693, to get

693 = 118 x 5 + 103

Step 3: We consider the new divisor 118 and the new remainder 103, and apply the division lemma to get

118 = 103 x 1 + 15

We consider the new divisor 103 and the new remainder 15,and apply the division lemma to get

103 = 15 x 6 + 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 811 and 693 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(103,15) = HCF(118,103) = HCF(693,118) = HCF(811,693) .

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

Step 1: Since 406 > 1, we apply the division lemma to 406 and 1, to get

406 = 1 x 406 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 406 is 1

Notice that 1 = HCF(406,1) .
