HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 6693, 7772 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 813, 6693, 7772 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, 6693, 7772 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, 6693, 7772 is 1.

HCF(813, 6693, 7772) = 1

Highest common factor (HCF) of 813, 6693, 7772 is 1.

Highest Common Factor of 813,6693,7772 using Euclid's algorithm

Highest Common Factor of 813,6693,7772 is 1

Step 1: Since 6693 > 813, we apply the division lemma to 6693 and 813, to get

6693 = 813 x 8 + 189

Step 2: Since the reminder 813 ≠ 0, we apply division lemma to 189 and 813, to get

813 = 189 x 4 + 57

Step 3: We consider the new divisor 189 and the new remainder 57, and apply the division lemma to get

189 = 57 x 3 + 18

We consider the new divisor 57 and the new remainder 18,and apply the division lemma to get

57 = 18 x 3 + 3

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

18 = 3 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 813 and 6693 is 3

Notice that 3 = HCF(18,3) = HCF(57,18) = HCF(189,57) = HCF(813,189) = HCF(6693,813) .

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

Step 1: Since 7772 > 3, we apply the division lemma to 7772 and 3, to get

7772 = 3 x 2590 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 7772 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(7772,3) .
