HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 903, 547, 343 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 903, 547, 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 903, 547, 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 903, 547, 343 is 1.

HCF(903, 547, 343) = 1

Highest common factor (HCF) of 903, 547, 343 is 1.

Highest Common Factor of 903,547,343 using Euclid's algorithm

Highest Common Factor of 903,547,343 is 1

Step 1: Since 903 > 547, we apply the division lemma to 903 and 547, to get

903 = 547 x 1 + 356

Step 2: Since the reminder 547 ≠ 0, we apply division lemma to 356 and 547, to get

547 = 356 x 1 + 191

Step 3: We consider the new divisor 356 and the new remainder 191, and apply the division lemma to get

356 = 191 x 1 + 165

We consider the new divisor 191 and the new remainder 165,and apply the division lemma to get

191 = 165 x 1 + 26

We consider the new divisor 165 and the new remainder 26,and apply the division lemma to get

165 = 26 x 6 + 9

We consider the new divisor 26 and the new remainder 9,and apply the division lemma to get

26 = 9 x 2 + 8

We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get

9 = 8 x 1 + 1

We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 903 and 547 is 1

Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(26,9) = HCF(165,26) = HCF(191,165) = HCF(356,191) = HCF(547,356) = HCF(903,547) .

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) .
