HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 492, 311, 371 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 492, 311, 371 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 492, 311, 371 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 492, 311, 371 is 1.

HCF(492, 311, 371) = 1

Highest Common Factor of 492,311,371 using Euclid's algorithm

Highest Common Factor of 492,311,371 is 1

Step 1: Since 492 > 311, we apply the division lemma to 492 and 311, to get

492 = 311 x 1 + 181

Step 2: Since the reminder 311 ≠ 0, we apply division lemma to 181 and 311, to get

311 = 181 x 1 + 130

Step 3: We consider the new divisor 181 and the new remainder 130, and apply the division lemma to get

181 = 130 x 1 + 51

We consider the new divisor 130 and the new remainder 51,and apply the division lemma to get

130 = 51 x 2 + 28

We consider the new divisor 51 and the new remainder 28,and apply the division lemma to get

51 = 28 x 1 + 23

We consider the new divisor 28 and the new remainder 23,and apply the division lemma to get

28 = 23 x 1 + 5

We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get

23 = 5 x 4 + 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 492 and 311 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(28,23) = HCF(51,28) = HCF(130,51) = HCF(181,130) = HCF(311,181) = HCF(492,311) .

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

Step 1: Since 371 > 1, we apply the division lemma to 371 and 1, to get

371 = 1 x 371 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 371 is 1

Notice that 1 = HCF(371,1) .
