HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 518, 949, 313 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 518, 949, 313 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 518, 949, 313 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 518, 949, 313 is 1.

HCF(518, 949, 313) = 1

HCF of 518, 949, 313 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 518, 949, 313 is 1.

Highest Common Factor of 518,949,313 using Euclid's algorithm

Highest Common Factor of 518,949,313 is 1

Step 1: Since 949 > 518, we apply the division lemma to 949 and 518, to get

949 = 518 x 1 + 431

Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 431 and 518, to get

518 = 431 x 1 + 87

Step 3: We consider the new divisor 431 and the new remainder 87, and apply the division lemma to get

431 = 87 x 4 + 83

We consider the new divisor 87 and the new remainder 83,and apply the division lemma to get

87 = 83 x 1 + 4

We consider the new divisor 83 and the new remainder 4,and apply the division lemma to get

83 = 4 x 20 + 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 518 and 949 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(83,4) = HCF(87,83) = HCF(431,87) = HCF(518,431) = HCF(949,518) .

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

Step 1: Since 313 > 1, we apply the division lemma to 313 and 1, to get

313 = 1 x 313 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 313 is 1

Notice that 1 = HCF(313,1) .
