HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 426, 727, 803 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 426, 727, 803 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 426, 727, 803 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 426, 727, 803 is 1.

HCF(426, 727, 803) = 1

Highest common factor (HCF) of 426, 727, 803 is 1.

Highest Common Factor of 426,727,803 using Euclid's algorithm

Highest Common Factor of 426,727,803 is 1

Step 1: Since 727 > 426, we apply the division lemma to 727 and 426, to get

727 = 426 x 1 + 301

Step 2: Since the reminder 426 ≠ 0, we apply division lemma to 301 and 426, to get

426 = 301 x 1 + 125

Step 3: We consider the new divisor 301 and the new remainder 125, and apply the division lemma to get

301 = 125 x 2 + 51

We consider the new divisor 125 and the new remainder 51,and apply the division lemma to get

125 = 51 x 2 + 23

We consider the new divisor 51 and the new remainder 23,and apply the division lemma to get

51 = 23 x 2 + 5

We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get

23 = 5 x 4 + 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 426 and 727 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(51,23) = HCF(125,51) = HCF(301,125) = HCF(426,301) = HCF(727,426) .

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

Step 1: Since 803 > 1, we apply the division lemma to 803 and 1, to get

803 = 1 x 803 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 803 is 1

Notice that 1 = HCF(803,1) .
