HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 903, 261, 997 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 903, 261, 997 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, 261, 997 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, 261, 997 is 1.

HCF(903, 261, 997) = 1

Highest common factor (HCF) of 903, 261, 997 is 1.

Highest Common Factor of 903,261,997 using Euclid's algorithm

Highest Common Factor of 903,261,997 is 1

Step 1: Since 903 > 261, we apply the division lemma to 903 and 261, to get

903 = 261 x 3 + 120

Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 120 and 261, to get

261 = 120 x 2 + 21

Step 3: We consider the new divisor 120 and the new remainder 21, and apply the division lemma to get

120 = 21 x 5 + 15

We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get

21 = 15 x 1 + 6

We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 903 and 261 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(120,21) = HCF(261,120) = HCF(903,261) .

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

Step 1: Since 997 > 3, we apply the division lemma to 997 and 3, to get

997 = 3 x 332 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 997 is 1

Notice that 1 = HCF(3,1) = HCF(997,3) .
