HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 683, 482, 309 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 683, 482, 309 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 683, 482, 309 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 683, 482, 309 is 1.

HCF(683, 482, 309) = 1

Highest common factor (HCF) of 683, 482, 309 is 1.

Highest Common Factor of 683,482,309 using Euclid's algorithm

Highest Common Factor of 683,482,309 is 1

Step 1: Since 683 > 482, we apply the division lemma to 683 and 482, to get

683 = 482 x 1 + 201

Step 2: Since the reminder 482 ≠ 0, we apply division lemma to 201 and 482, to get

482 = 201 x 2 + 80

Step 3: We consider the new divisor 201 and the new remainder 80, and apply the division lemma to get

201 = 80 x 2 + 41

We consider the new divisor 80 and the new remainder 41,and apply the division lemma to get

80 = 41 x 1 + 39

We consider the new divisor 41 and the new remainder 39,and apply the division lemma to get

41 = 39 x 1 + 2

We consider the new divisor 39 and the new remainder 2,and apply the division lemma to get

39 = 2 x 19 + 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 683 and 482 is 1

Notice that 1 = HCF(2,1) = HCF(39,2) = HCF(41,39) = HCF(80,41) = HCF(201,80) = HCF(482,201) = HCF(683,482) .

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

Step 1: Since 309 > 1, we apply the division lemma to 309 and 1, to get

309 = 1 x 309 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 309 is 1

Notice that 1 = HCF(309,1) .
