HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 677, 418, 807 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 677, 418, 807 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 677, 418, 807 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 677, 418, 807 is 1.

HCF(677, 418, 807) = 1

Highest common factor (HCF) of 677, 418, 807 is 1.

Highest Common Factor of 677,418,807 using Euclid's algorithm

Highest Common Factor of 677,418,807 is 1

Step 1: Since 677 > 418, we apply the division lemma to 677 and 418, to get

677 = 418 x 1 + 259

Step 2: Since the reminder 418 ≠ 0, we apply division lemma to 259 and 418, to get

418 = 259 x 1 + 159

Step 3: We consider the new divisor 259 and the new remainder 159, and apply the division lemma to get

259 = 159 x 1 + 100

We consider the new divisor 159 and the new remainder 100,and apply the division lemma to get

159 = 100 x 1 + 59

We consider the new divisor 100 and the new remainder 59,and apply the division lemma to get

100 = 59 x 1 + 41

We consider the new divisor 59 and the new remainder 41,and apply the division lemma to get

59 = 41 x 1 + 18

We consider the new divisor 41 and the new remainder 18,and apply the division lemma to get

41 = 18 x 2 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 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 677 and 418 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(41,18) = HCF(59,41) = HCF(100,59) = HCF(159,100) = HCF(259,159) = HCF(418,259) = HCF(677,418) .

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

Step 1: Since 807 > 1, we apply the division lemma to 807 and 1, to get

807 = 1 x 807 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 807 is 1

Notice that 1 = HCF(807,1) .
