HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 518, 845, 491 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 518, 845, 491 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 518, 845, 491 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 518, 845, 491 is 1.

HCF(518, 845, 491) = 1

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

HCF of:

Highest common factor (HCF) of 518, 845, 491 is 1.

Highest Common Factor of 518,845,491 using Euclid's algorithm

Highest Common Factor of 518,845,491 is 1

Step 1: Since 845 > 518, we apply the division lemma to 845 and 518, to get

845 = 518 x 1 + 327

Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 327 and 518, to get

518 = 327 x 1 + 191

Step 3: We consider the new divisor 327 and the new remainder 191, and apply the division lemma to get

327 = 191 x 1 + 136

We consider the new divisor 191 and the new remainder 136,and apply the division lemma to get

191 = 136 x 1 + 55

We consider the new divisor 136 and the new remainder 55,and apply the division lemma to get

136 = 55 x 2 + 26

We consider the new divisor 55 and the new remainder 26,and apply the division lemma to get

55 = 26 x 2 + 3

We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get

26 = 3 x 8 + 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 518 and 845 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(55,26) = HCF(136,55) = HCF(191,136) = HCF(327,191) = HCF(518,327) = HCF(845,518) .

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

Step 1: Since 491 > 1, we apply the division lemma to 491 and 1, to get

491 = 1 x 491 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 491 is 1

Notice that 1 = HCF(491,1) .
