HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 450, 317 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 997, 450, 317 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, 450, 317 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, 450, 317 is 1.

HCF(997, 450, 317) = 1

HCF of 997, 450, 317 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, 450, 317 is 1.

Highest Common Factor of 997,450,317 using Euclid's algorithm

Highest Common Factor of 997,450,317 is 1

Step 1: Since 997 > 450, we apply the division lemma to 997 and 450, to get

997 = 450 x 2 + 97

Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 97 and 450, to get

450 = 97 x 4 + 62

Step 3: We consider the new divisor 97 and the new remainder 62, and apply the division lemma to get

97 = 62 x 1 + 35

We consider the new divisor 62 and the new remainder 35,and apply the division lemma to get

62 = 35 x 1 + 27

We consider the new divisor 35 and the new remainder 27,and apply the division lemma to get

35 = 27 x 1 + 8

We consider the new divisor 27 and the new remainder 8,and apply the division lemma to get

27 = 8 x 3 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 997 and 450 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(27,8) = HCF(35,27) = HCF(62,35) = HCF(97,62) = HCF(450,97) = HCF(997,450) .

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

Step 1: Since 317 > 1, we apply the division lemma to 317 and 1, to get

317 = 1 x 317 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 317 is 1

Notice that 1 = HCF(317,1) .
