HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 318, 535, 115 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 318, 535, 115 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 318, 535, 115 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 318, 535, 115 is 1.

HCF(318, 535, 115) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 318, 535, 115 is 1.

Highest Common Factor of 318,535,115 using Euclid's algorithm

Highest Common Factor of 318,535,115 is 1

Step 1: Since 535 > 318, we apply the division lemma to 535 and 318, to get

535 = 318 x 1 + 217

Step 2: Since the reminder 318 ≠ 0, we apply division lemma to 217 and 318, to get

318 = 217 x 1 + 101

Step 3: We consider the new divisor 217 and the new remainder 101, and apply the division lemma to get

217 = 101 x 2 + 15

We consider the new divisor 101 and the new remainder 15,and apply the division lemma to get

101 = 15 x 6 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 318 and 535 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(101,15) = HCF(217,101) = HCF(318,217) = HCF(535,318) .

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

Step 1: Since 115 > 1, we apply the division lemma to 115 and 1, to get

115 = 1 x 115 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 115 is 1

Notice that 1 = HCF(115,1) .
