HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 687, 91, 584 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 687, 91, 584 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 687, 91, 584 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 687, 91, 584 is 1.

HCF(687, 91, 584) = 1

HCF of 687, 91, 584 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 687, 91, 584 is 1.

Highest Common Factor of 687,91,584 using Euclid's algorithm

Highest Common Factor of 687,91,584 is 1

Step 1: Since 687 > 91, we apply the division lemma to 687 and 91, to get

687 = 91 x 7 + 50

Step 2: Since the reminder 91 ≠ 0, we apply division lemma to 50 and 91, to get

91 = 50 x 1 + 41

Step 3: We consider the new divisor 50 and the new remainder 41, and apply the division lemma to get

50 = 41 x 1 + 9

We consider the new divisor 41 and the new remainder 9,and apply the division lemma to get

41 = 9 x 4 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 687 and 91 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(41,9) = HCF(50,41) = HCF(91,50) = HCF(687,91) .

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

Step 1: Since 584 > 1, we apply the division lemma to 584 and 1, to get

584 = 1 x 584 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 584 is 1

Notice that 1 = HCF(584,1) .
