HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 817, 497, 343 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 817, 497, 343 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 817, 497, 343 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 817, 497, 343 is 1.

HCF(817, 497, 343) = 1

HCF of 817, 497, 343 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 817, 497, 343 is 1.

Highest Common Factor of 817,497,343 using Euclid's algorithm

Highest Common Factor of 817,497,343 is 1

Step 1: Since 817 > 497, we apply the division lemma to 817 and 497, to get

817 = 497 x 1 + 320

Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 320 and 497, to get

497 = 320 x 1 + 177

Step 3: We consider the new divisor 320 and the new remainder 177, and apply the division lemma to get

320 = 177 x 1 + 143

We consider the new divisor 177 and the new remainder 143,and apply the division lemma to get

177 = 143 x 1 + 34

We consider the new divisor 143 and the new remainder 34,and apply the division lemma to get

143 = 34 x 4 + 7

We consider the new divisor 34 and the new remainder 7,and apply the division lemma to get

34 = 7 x 4 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 817 and 497 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(34,7) = HCF(143,34) = HCF(177,143) = HCF(320,177) = HCF(497,320) = HCF(817,497) .

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

Step 1: Since 343 > 1, we apply the division lemma to 343 and 1, to get

343 = 1 x 343 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 343 is 1

Notice that 1 = HCF(343,1) .
