HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 258, 683 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 997, 258, 683 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 997, 258, 683 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 997, 258, 683 is 1.

HCF(997, 258, 683) = 1

HCF of 997, 258, 683 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 997, 258, 683 is 1.

Highest Common Factor of 997,258,683 using Euclid's algorithm

Highest Common Factor of 997,258,683 is 1

Step 1: Since 997 > 258, we apply the division lemma to 997 and 258, to get

997 = 258 x 3 + 223

Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 223 and 258, to get

258 = 223 x 1 + 35

Step 3: We consider the new divisor 223 and the new remainder 35, and apply the division lemma to get

223 = 35 x 6 + 13

We consider the new divisor 35 and the new remainder 13,and apply the division lemma to get

35 = 13 x 2 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 997 and 258 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(35,13) = HCF(223,35) = HCF(258,223) = HCF(997,258) .

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

Step 1: Since 683 > 1, we apply the division lemma to 683 and 1, to get

683 = 1 x 683 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 683 is 1

Notice that 1 = HCF(683,1) .
