HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 682, 797, 447 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 682, 797, 447 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 682, 797, 447 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 682, 797, 447 is 1.

HCF(682, 797, 447) = 1

HCF of 682, 797, 447 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 682, 797, 447 is 1.

Highest Common Factor of 682,797,447 using Euclid's algorithm

Highest Common Factor of 682,797,447 is 1

Step 1: Since 797 > 682, we apply the division lemma to 797 and 682, to get

797 = 682 x 1 + 115

Step 2: Since the reminder 682 ≠ 0, we apply division lemma to 115 and 682, to get

682 = 115 x 5 + 107

Step 3: We consider the new divisor 115 and the new remainder 107, and apply the division lemma to get

115 = 107 x 1 + 8

We consider the new divisor 107 and the new remainder 8,and apply the division lemma to get

107 = 8 x 13 + 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 682 and 797 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(107,8) = HCF(115,107) = HCF(682,115) = HCF(797,682) .

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

Step 1: Since 447 > 1, we apply the division lemma to 447 and 1, to get

447 = 1 x 447 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 447 is 1

Notice that 1 = HCF(447,1) .
