HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 317, 459 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 317, 459 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 317, 459 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 317, 459 is 1.

HCF(317, 459) = 1

HCF of 317, 459 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 317, 459 is 1.

Highest Common Factor of 317,459 using Euclid's algorithm

Highest Common Factor of 317,459 is 1

Step 1: Since 459 > 317, we apply the division lemma to 459 and 317, to get

459 = 317 x 1 + 142

Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 142 and 317, to get

317 = 142 x 2 + 33

Step 3: We consider the new divisor 142 and the new remainder 33, and apply the division lemma to get

142 = 33 x 4 + 10

We consider the new divisor 33 and the new remainder 10,and apply the division lemma to get

33 = 10 x 3 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 317 and 459 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(33,10) = HCF(142,33) = HCF(317,142) = HCF(459,317) .
