HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 586, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 818, 586, 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 818, 586, 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 818, 586, 257 is 1.

HCF(818, 586, 257) = 1

Highest common factor (HCF) of 818, 586, 257 is 1.

Highest Common Factor of 818,586,257 using Euclid's algorithm

Highest Common Factor of 818,586,257 is 1

Step 1: Since 818 > 586, we apply the division lemma to 818 and 586, to get

818 = 586 x 1 + 232

Step 2: Since the reminder 586 ≠ 0, we apply division lemma to 232 and 586, to get

586 = 232 x 2 + 122

Step 3: We consider the new divisor 232 and the new remainder 122, and apply the division lemma to get

232 = 122 x 1 + 110

We consider the new divisor 122 and the new remainder 110,and apply the division lemma to get

122 = 110 x 1 + 12

We consider the new divisor 110 and the new remainder 12,and apply the division lemma to get

110 = 12 x 9 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 818 and 586 is 2

Notice that 2 = HCF(12,2) = HCF(110,12) = HCF(122,110) = HCF(232,122) = HCF(586,232) = HCF(818,586) .

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

Step 1: Since 257 > 2, we apply the division lemma to 257 and 2, to get

257 = 2 x 128 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 257 is 1

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