HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 866, 221, 683 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 866, 221, 683 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 866, 221, 683 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 866, 221, 683 is 1.

HCF(866, 221, 683) = 1

HCF of 866, 221, 683 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 866, 221, 683 is 1.

Highest Common Factor of 866,221,683 using Euclid's algorithm

Highest Common Factor of 866,221,683 is 1

Step 1: Since 866 > 221, we apply the division lemma to 866 and 221, to get

866 = 221 x 3 + 203

Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 203 and 221, to get

221 = 203 x 1 + 18

Step 3: We consider the new divisor 203 and the new remainder 18, and apply the division lemma to get

203 = 18 x 11 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 866 and 221 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(203,18) = HCF(221,203) = HCF(866,221) .

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

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

683 = 1 x 683 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 683 is 1

Notice that 1 = HCF(683,1) .
