HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 503, 201, 866 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 503, 201, 866 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 503, 201, 866 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 503, 201, 866 is 1.

HCF(503, 201, 866) = 1

HCF of 503, 201, 866 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 503, 201, 866 is 1.

Highest Common Factor of 503,201,866 using Euclid's algorithm

Highest Common Factor of 503,201,866 is 1

Step 1: Since 503 > 201, we apply the division lemma to 503 and 201, to get

503 = 201 x 2 + 101

Step 2: Since the reminder 201 ≠ 0, we apply division lemma to 101 and 201, to get

201 = 101 x 1 + 100

Step 3: We consider the new divisor 101 and the new remainder 100, and apply the division lemma to get

101 = 100 x 1 + 1

We consider the new divisor 100 and the new remainder 1, and apply the division lemma to get

100 = 1 x 100 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 503 and 201 is 1

Notice that 1 = HCF(100,1) = HCF(101,100) = HCF(201,101) = HCF(503,201) .


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

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

866 = 1 x 866 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 866 is 1

Notice that 1 = HCF(866,1) .
