HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 811, 97 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 997, 811, 97 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 997, 811, 97 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 997, 811, 97 is 1.

HCF(997, 811, 97) = 1

Highest common factor (HCF) of 997, 811, 97 is 1.

Highest Common Factor of 997,811,97 using Euclid's algorithm

Highest Common Factor of 997,811,97 is 1

Step 1: Since 997 > 811, we apply the division lemma to 997 and 811, to get

997 = 811 x 1 + 186

Step 2: Since the reminder 811 ≠ 0, we apply division lemma to 186 and 811, to get

811 = 186 x 4 + 67

Step 3: We consider the new divisor 186 and the new remainder 67, and apply the division lemma to get

186 = 67 x 2 + 52

We consider the new divisor 67 and the new remainder 52,and apply the division lemma to get

67 = 52 x 1 + 15

We consider the new divisor 52 and the new remainder 15,and apply the division lemma to get

52 = 15 x 3 + 7

We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get

15 = 7 x 2 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 997 and 811 is 1

Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(52,15) = HCF(67,52) = HCF(186,67) = HCF(811,186) = HCF(997,811) .

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

Step 1: Since 97 > 1, we apply the division lemma to 97 and 1, to get

97 = 1 x 97 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 97 is 1

Notice that 1 = HCF(97,1) .
