HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 747, 491, 582 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 747, 491, 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 747, 491, 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 747, 491, 582 is 1.

HCF(747, 491, 582) = 1

HCF of 747, 491, 582 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 747, 491, 582 is 1.

Highest Common Factor of 747,491,582 using Euclid's algorithm

Highest Common Factor of 747,491,582 is 1

Step 1: Since 747 > 491, we apply the division lemma to 747 and 491, to get

747 = 491 x 1 + 256

Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 256 and 491, to get

491 = 256 x 1 + 235

Step 3: We consider the new divisor 256 and the new remainder 235, and apply the division lemma to get

256 = 235 x 1 + 21

We consider the new divisor 235 and the new remainder 21,and apply the division lemma to get

235 = 21 x 11 + 4

We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get

21 = 4 x 5 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 747 and 491 is 1

Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(235,21) = HCF(256,235) = HCF(491,256) = HCF(747,491) .

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) .
