HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 530, 203 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 863, 530, 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 863, 530, 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 863, 530, 203 is 1.

HCF(863, 530, 203) = 1

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

HCF of:

Highest common factor (HCF) of 863, 530, 203 is 1.

Highest Common Factor of 863,530,203 using Euclid's algorithm

Highest Common Factor of 863,530,203 is 1

Step 1: Since 863 > 530, we apply the division lemma to 863 and 530, to get

863 = 530 x 1 + 333

Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 333 and 530, to get

530 = 333 x 1 + 197

Step 3: We consider the new divisor 333 and the new remainder 197, and apply the division lemma to get

333 = 197 x 1 + 136

We consider the new divisor 197 and the new remainder 136,and apply the division lemma to get

197 = 136 x 1 + 61

We consider the new divisor 136 and the new remainder 61,and apply the division lemma to get

136 = 61 x 2 + 14

We consider the new divisor 61 and the new remainder 14,and apply the division lemma to get

61 = 14 x 4 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 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 863 and 530 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(61,14) = HCF(136,61) = HCF(197,136) = HCF(333,197) = HCF(530,333) = HCF(863,530) .

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

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

203 = 1 x 203 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 203 is 1

Notice that 1 = HCF(203,1) .
