HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 806, 566, 203 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 806, 566, 203 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 806, 566, 203 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 806, 566, 203 is 1.

HCF(806, 566, 203) = 1

Highest Common Factor of 806,566,203 using Euclid's algorithm

Highest Common Factor of 806,566,203 is 1

Step 1: Since 806 > 566, we apply the division lemma to 806 and 566, to get

806 = 566 x 1 + 240

Step 2: Since the reminder 566 ≠ 0, we apply division lemma to 240 and 566, to get

566 = 240 x 2 + 86

Step 3: We consider the new divisor 240 and the new remainder 86, and apply the division lemma to get

240 = 86 x 2 + 68

We consider the new divisor 86 and the new remainder 68,and apply the division lemma to get

86 = 68 x 1 + 18

We consider the new divisor 68 and the new remainder 18,and apply the division lemma to get

68 = 18 x 3 + 14

We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get

18 = 14 x 1 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 806 and 566 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(68,18) = HCF(86,68) = HCF(240,86) = HCF(566,240) = HCF(806,566) .

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

Step 1: Since 203 > 2, we apply the division lemma to 203 and 2, to get

203 = 2 x 101 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 203 is 1

Notice that 1 = HCF(2,1) = HCF(203,2) .
