HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 808, 7693 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 808, 7693 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 808, 7693 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 808, 7693 is 1.

HCF(808, 7693) = 1

Highest common factor (HCF) of 808, 7693 is 1.

Highest Common Factor of 808,7693 using Euclid's algorithm

Highest Common Factor of 808,7693 is 1

Step 1: Since 7693 > 808, we apply the division lemma to 7693 and 808, to get

7693 = 808 x 9 + 421

Step 2: Since the reminder 808 ≠ 0, we apply division lemma to 421 and 808, to get

808 = 421 x 1 + 387

Step 3: We consider the new divisor 421 and the new remainder 387, and apply the division lemma to get

421 = 387 x 1 + 34

We consider the new divisor 387 and the new remainder 34,and apply the division lemma to get

387 = 34 x 11 + 13

We consider the new divisor 34 and the new remainder 13,and apply the division lemma to get

34 = 13 x 2 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 808 and 7693 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(34,13) = HCF(387,34) = HCF(421,387) = HCF(808,421) = HCF(7693,808) .
