HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 877, 686 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 818, 877, 686 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 818, 877, 686 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 818, 877, 686 is 1.

HCF(818, 877, 686) = 1

Highest common factor (HCF) of 818, 877, 686 is 1.

Highest Common Factor of 818,877,686 using Euclid's algorithm

Highest Common Factor of 818,877,686 is 1

Step 1: Since 877 > 818, we apply the division lemma to 877 and 818, to get

877 = 818 x 1 + 59

Step 2: Since the reminder 818 ≠ 0, we apply division lemma to 59 and 818, to get

818 = 59 x 13 + 51

Step 3: We consider the new divisor 59 and the new remainder 51, and apply the division lemma to get

59 = 51 x 1 + 8

We consider the new divisor 51 and the new remainder 8,and apply the division lemma to get

51 = 8 x 6 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 818 and 877 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(51,8) = HCF(59,51) = HCF(818,59) = HCF(877,818) .

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

Step 1: Since 686 > 1, we apply the division lemma to 686 and 1, to get

686 = 1 x 686 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 686 is 1

Notice that 1 = HCF(686,1) .
