HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 563, 682, 812 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 563, 682, 812 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 563, 682, 812 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 563, 682, 812 is 1.

HCF(563, 682, 812) = 1

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

HCF of:

Highest common factor (HCF) of 563, 682, 812 is 1.

Highest Common Factor of 563,682,812 using Euclid's algorithm

Highest Common Factor of 563,682,812 is 1

Step 1: Since 682 > 563, we apply the division lemma to 682 and 563, to get

682 = 563 x 1 + 119

Step 2: Since the reminder 563 ≠ 0, we apply division lemma to 119 and 563, to get

563 = 119 x 4 + 87

Step 3: We consider the new divisor 119 and the new remainder 87, and apply the division lemma to get

119 = 87 x 1 + 32

We consider the new divisor 87 and the new remainder 32,and apply the division lemma to get

87 = 32 x 2 + 23

We consider the new divisor 32 and the new remainder 23,and apply the division lemma to get

32 = 23 x 1 + 9

We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get

23 = 9 x 2 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 563 and 682 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(32,23) = HCF(87,32) = HCF(119,87) = HCF(563,119) = HCF(682,563) .

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

Step 1: Since 812 > 1, we apply the division lemma to 812 and 1, to get

812 = 1 x 812 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 812 is 1

Notice that 1 = HCF(812,1) .
