HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 403, 656, 814 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 403, 656, 814 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 403, 656, 814 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 403, 656, 814 is 1.

HCF(403, 656, 814) = 1

HCF of 403, 656, 814 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 403, 656, 814 is 1.

Highest Common Factor of 403,656,814 using Euclid's algorithm

Highest Common Factor of 403,656,814 is 1

Step 1: Since 656 > 403, we apply the division lemma to 656 and 403, to get

656 = 403 x 1 + 253

Step 2: Since the reminder 403 ≠ 0, we apply division lemma to 253 and 403, to get

403 = 253 x 1 + 150

Step 3: We consider the new divisor 253 and the new remainder 150, and apply the division lemma to get

253 = 150 x 1 + 103

We consider the new divisor 150 and the new remainder 103,and apply the division lemma to get

150 = 103 x 1 + 47

We consider the new divisor 103 and the new remainder 47,and apply the division lemma to get

103 = 47 x 2 + 9

We consider the new divisor 47 and the new remainder 9,and apply the division lemma to get

47 = 9 x 5 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 403 and 656 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(47,9) = HCF(103,47) = HCF(150,103) = HCF(253,150) = HCF(403,253) = HCF(656,403) .

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

Step 1: Since 814 > 1, we apply the division lemma to 814 and 1, to get

814 = 1 x 814 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 814 is 1

Notice that 1 = HCF(814,1) .
