HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 508, 98 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 997, 508, 98 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, 508, 98 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, 508, 98 is 1.

HCF(997, 508, 98) = 1

HCF of 997, 508, 98 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 997, 508, 98 is 1.

Highest Common Factor of 997,508,98 using Euclid's algorithm

Highest Common Factor of 997,508,98 is 1

Step 1: Since 997 > 508, we apply the division lemma to 997 and 508, to get

997 = 508 x 1 + 489

Step 2: Since the reminder 508 ≠ 0, we apply division lemma to 489 and 508, to get

508 = 489 x 1 + 19

Step 3: We consider the new divisor 489 and the new remainder 19, and apply the division lemma to get

489 = 19 x 25 + 14

We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get

19 = 14 x 1 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 997 and 508 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(489,19) = HCF(508,489) = HCF(997,508) .

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

Step 1: Since 98 > 1, we apply the division lemma to 98 and 1, to get

98 = 1 x 98 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 98 is 1

Notice that 1 = HCF(98,1) .
