HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 481, 806, 399 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 481, 806, 399 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 481, 806, 399 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 481, 806, 399 is 1.

HCF(481, 806, 399) = 1

HCF of 481, 806, 399 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 481, 806, 399 is 1.

Highest Common Factor of 481,806,399 using Euclid's algorithm

Highest Common Factor of 481,806,399 is 1

Step 1: Since 806 > 481, we apply the division lemma to 806 and 481, to get

806 = 481 x 1 + 325

Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 325 and 481, to get

481 = 325 x 1 + 156

Step 3: We consider the new divisor 325 and the new remainder 156, and apply the division lemma to get

325 = 156 x 2 + 13

We consider the new divisor 156 and the new remainder 13, and apply the division lemma to get

156 = 13 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 481 and 806 is 13

Notice that 13 = HCF(156,13) = HCF(325,156) = HCF(481,325) = HCF(806,481) .

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

Step 1: Since 399 > 13, we apply the division lemma to 399 and 13, to get

399 = 13 x 30 + 9

Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 9 and 13, to get

13 = 9 x 1 + 4

Step 3: We consider the new divisor 9 and the new remainder 4, and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 399 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(399,13) .
