HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 798, 582 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 491, 798, 582 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 491, 798, 582 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 491, 798, 582 is 1.

HCF(491, 798, 582) = 1

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

HCF of:

Highest common factor (HCF) of 491, 798, 582 is 1.

Highest Common Factor of 491,798,582 using Euclid's algorithm

Highest Common Factor of 491,798,582 is 1

Step 1: Since 798 > 491, we apply the division lemma to 798 and 491, to get

798 = 491 x 1 + 307

Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 307 and 491, to get

491 = 307 x 1 + 184

Step 3: We consider the new divisor 307 and the new remainder 184, and apply the division lemma to get

307 = 184 x 1 + 123

We consider the new divisor 184 and the new remainder 123,and apply the division lemma to get

184 = 123 x 1 + 61

We consider the new divisor 123 and the new remainder 61,and apply the division lemma to get

123 = 61 x 2 + 1

We consider the new divisor 61 and the new remainder 1,and apply the division lemma to get

61 = 1 x 61 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 491 and 798 is 1

Notice that 1 = HCF(61,1) = HCF(123,61) = HCF(184,123) = HCF(307,184) = HCF(491,307) = HCF(798,491) .

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

Step 1: Since 582 > 1, we apply the division lemma to 582 and 1, to get

582 = 1 x 582 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 582 is 1

Notice that 1 = HCF(582,1) .
