HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 203, 788, 206 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 203, 788, 206 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 203, 788, 206 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 203, 788, 206 is 1.

HCF(203, 788, 206) = 1

HCF of 203, 788, 206 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 203, 788, 206 is 1.

Highest Common Factor of 203,788,206 using Euclid's algorithm

Highest Common Factor of 203,788,206 is 1

Step 1: Since 788 > 203, we apply the division lemma to 788 and 203, to get

788 = 203 x 3 + 179

Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 179 and 203, to get

203 = 179 x 1 + 24

Step 3: We consider the new divisor 179 and the new remainder 24, and apply the division lemma to get

179 = 24 x 7 + 11

We consider the new divisor 24 and the new remainder 11,and apply the division lemma to get

24 = 11 x 2 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 203 and 788 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(24,11) = HCF(179,24) = HCF(203,179) = HCF(788,203) .

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

Step 1: Since 206 > 1, we apply the division lemma to 206 and 1, to get

206 = 1 x 206 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 206 is 1

Notice that 1 = HCF(206,1) .
