HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 331, 408 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 813, 331, 408 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 813, 331, 408 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 813, 331, 408 is 1.

HCF(813, 331, 408) = 1

Highest common factor (HCF) of 813, 331, 408 is 1.

Highest Common Factor of 813,331,408 using Euclid's algorithm

Highest Common Factor of 813,331,408 is 1

Step 1: Since 813 > 331, we apply the division lemma to 813 and 331, to get

813 = 331 x 2 + 151

Step 2: Since the reminder 331 ≠ 0, we apply division lemma to 151 and 331, to get

331 = 151 x 2 + 29

Step 3: We consider the new divisor 151 and the new remainder 29, and apply the division lemma to get

151 = 29 x 5 + 6

We consider the new divisor 29 and the new remainder 6,and apply the division lemma to get

29 = 6 x 4 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 813 and 331 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(29,6) = HCF(151,29) = HCF(331,151) = HCF(813,331) .

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

Step 1: Since 408 > 1, we apply the division lemma to 408 and 1, to get

408 = 1 x 408 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 408 is 1

Notice that 1 = HCF(408,1) .
