HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 311, 818, 533 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 311, 818, 533 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 311, 818, 533 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 311, 818, 533 is 1.

HCF(311, 818, 533) = 1

Highest common factor (HCF) of 311, 818, 533 is 1.

Highest Common Factor of 311,818,533 using Euclid's algorithm

Highest Common Factor of 311,818,533 is 1

Step 1: Since 818 > 311, we apply the division lemma to 818 and 311, to get

818 = 311 x 2 + 196

Step 2: Since the reminder 311 ≠ 0, we apply division lemma to 196 and 311, to get

311 = 196 x 1 + 115

Step 3: We consider the new divisor 196 and the new remainder 115, and apply the division lemma to get

196 = 115 x 1 + 81

We consider the new divisor 115 and the new remainder 81,and apply the division lemma to get

115 = 81 x 1 + 34

We consider the new divisor 81 and the new remainder 34,and apply the division lemma to get

81 = 34 x 2 + 13

We consider the new divisor 34 and the new remainder 13,and apply the division lemma to get

34 = 13 x 2 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 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 311 and 818 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(34,13) = HCF(81,34) = HCF(115,81) = HCF(196,115) = HCF(311,196) = HCF(818,311) .

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

Step 1: Since 533 > 1, we apply the division lemma to 533 and 1, to get

533 = 1 x 533 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 533 is 1

Notice that 1 = HCF(533,1) .
