HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 393, 494 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 811, 393, 494 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, 393, 494 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, 393, 494 is 1.

HCF(811, 393, 494) = 1

Highest common factor (HCF) of 811, 393, 494 is 1.

Highest Common Factor of 811,393,494 using Euclid's algorithm

Highest Common Factor of 811,393,494 is 1

Step 1: Since 811 > 393, we apply the division lemma to 811 and 393, to get

811 = 393 x 2 + 25

Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 25 and 393, to get

393 = 25 x 15 + 18

Step 3: We consider the new divisor 25 and the new remainder 18, and apply the division lemma to get

25 = 18 x 1 + 7

We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get

18 = 7 x 2 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 811 and 393 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(393,25) = HCF(811,393) .

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

Step 1: Since 494 > 1, we apply the division lemma to 494 and 1, to get

494 = 1 x 494 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 494 is 1

Notice that 1 = HCF(494,1) .
