HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 685, 976, 583 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 685, 976, 583 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 685, 976, 583 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 685, 976, 583 is 1.

HCF(685, 976, 583) = 1

Highest common factor (HCF) of 685, 976, 583 is 1.

Highest Common Factor of 685,976,583 using Euclid's algorithm

Highest Common Factor of 685,976,583 is 1

Step 1: Since 976 > 685, we apply the division lemma to 976 and 685, to get

976 = 685 x 1 + 291

Step 2: Since the reminder 685 ≠ 0, we apply division lemma to 291 and 685, to get

685 = 291 x 2 + 103

Step 3: We consider the new divisor 291 and the new remainder 103, and apply the division lemma to get

291 = 103 x 2 + 85

We consider the new divisor 103 and the new remainder 85,and apply the division lemma to get

103 = 85 x 1 + 18

We consider the new divisor 85 and the new remainder 18,and apply the division lemma to get

85 = 18 x 4 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 685 and 976 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(85,18) = HCF(103,85) = HCF(291,103) = HCF(685,291) = HCF(976,685) .

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

Step 1: Since 583 > 1, we apply the division lemma to 583 and 1, to get

583 = 1 x 583 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 583 is 1

Notice that 1 = HCF(583,1) .
