HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 677, 758, 255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 677, 758, 255 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, 758, 255 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, 758, 255 is 1.

HCF(677, 758, 255) = 1

HCF of 677, 758, 255 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 677, 758, 255 is 1.

Highest Common Factor of 677,758,255 using Euclid's algorithm

Highest Common Factor of 677,758,255 is 1

Step 1: Since 758 > 677, we apply the division lemma to 758 and 677, to get

758 = 677 x 1 + 81

Step 2: Since the reminder 677 ≠ 0, we apply division lemma to 81 and 677, to get

677 = 81 x 8 + 29

Step 3: We consider the new divisor 81 and the new remainder 29, and apply the division lemma to get

81 = 29 x 2 + 23

We consider the new divisor 29 and the new remainder 23,and apply the division lemma to get

29 = 23 x 1 + 6

We consider the new divisor 23 and the new remainder 6,and apply the division lemma to get

23 = 6 x 3 + 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 677 and 758 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(29,23) = HCF(81,29) = HCF(677,81) = HCF(758,677) .

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

Step 1: Since 255 > 1, we apply the division lemma to 255 and 1, to get

255 = 1 x 255 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 255 is 1

Notice that 1 = HCF(255,1) .
