HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 657, 814 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 404, 657, 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 404, 657, 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 404, 657, 814 is 1.

HCF(404, 657, 814) = 1

HCF of 404, 657, 814 using Euclid's algorithm

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

Highest common factor (HCF) of 404, 657, 814 is 1.

Highest Common Factor of 404,657,814 using Euclid's algorithm

Highest Common Factor of 404,657,814 is 1

Step 1: Since 657 > 404, we apply the division lemma to 657 and 404, to get

657 = 404 x 1 + 253

Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 253 and 404, to get

404 = 253 x 1 + 151

Step 3: We consider the new divisor 253 and the new remainder 151, and apply the division lemma to get

253 = 151 x 1 + 102

We consider the new divisor 151 and the new remainder 102,and apply the division lemma to get

151 = 102 x 1 + 49

We consider the new divisor 102 and the new remainder 49,and apply the division lemma to get

102 = 49 x 2 + 4

We consider the new divisor 49 and the new remainder 4,and apply the division lemma to get

49 = 4 x 12 + 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 404 and 657 is 1

Notice that 1 = HCF(4,1) = HCF(49,4) = HCF(102,49) = HCF(151,102) = HCF(253,151) = HCF(404,253) = HCF(657,404) .

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) .
