HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 258, 813, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 855, 258, 813, 257 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 855, 258, 813, 257 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 855, 258, 813, 257 is 1.

HCF(855, 258, 813, 257) = 1

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

HCF of:

Highest common factor (HCF) of 855, 258, 813, 257 is 1.

Highest Common Factor of 855,258,813,257 using Euclid's algorithm

Highest Common Factor of 855,258,813,257 is 1

Step 1: Since 855 > 258, we apply the division lemma to 855 and 258, to get

855 = 258 x 3 + 81

Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 81 and 258, to get

258 = 81 x 3 + 15

Step 3: We consider the new divisor 81 and the new remainder 15, and apply the division lemma to get

81 = 15 x 5 + 6

We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 855 and 258 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(81,15) = HCF(258,81) = HCF(855,258) .

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

Step 1: Since 813 > 3, we apply the division lemma to 813 and 3, to get

813 = 3 x 271 + 0

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

Notice that 3 = HCF(813,3) .

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

Step 1: Since 257 > 3, we apply the division lemma to 257 and 3, to get

257 = 3 x 85 + 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 257 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(257,3) .
