HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 482, 781, 997 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 482, 781, 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 482, 781, 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 482, 781, 997 is 1.

HCF(482, 781, 997) = 1

Highest Common Factor of 482,781,997 using Euclid's algorithm

Highest Common Factor of 482,781,997 is 1

Step 1: Since 781 > 482, we apply the division lemma to 781 and 482, to get

781 = 482 x 1 + 299

Step 2: Since the reminder 482 ≠ 0, we apply division lemma to 299 and 482, to get

482 = 299 x 1 + 183

Step 3: We consider the new divisor 299 and the new remainder 183, and apply the division lemma to get

299 = 183 x 1 + 116

We consider the new divisor 183 and the new remainder 116,and apply the division lemma to get

183 = 116 x 1 + 67

We consider the new divisor 116 and the new remainder 67,and apply the division lemma to get

116 = 67 x 1 + 49

We consider the new divisor 67 and the new remainder 49,and apply the division lemma to get

67 = 49 x 1 + 18

We consider the new divisor 49 and the new remainder 18,and apply the division lemma to get

49 = 18 x 2 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 482 and 781 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(49,18) = HCF(67,49) = HCF(116,67) = HCF(183,116) = HCF(299,183) = HCF(482,299) = HCF(781,482) .


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

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

997 = 1 x 997 + 0

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

Notice that 1 = HCF(997,1) .
