HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 186, 518 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 520, 186, 518 is 2 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 520, 186, 518 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 520, 186, 518 is 2.

HCF(520, 186, 518) = 2

HCF of 520, 186, 518 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 520, 186, 518 is 2.

Highest Common Factor of 520,186,518 using Euclid's algorithm

Highest Common Factor of 520,186,518 is 2

Step 1: Since 520 > 186, we apply the division lemma to 520 and 186, to get

520 = 186 x 2 + 148

Step 2: Since the reminder 186 ≠ 0, we apply division lemma to 148 and 186, to get

186 = 148 x 1 + 38

Step 3: We consider the new divisor 148 and the new remainder 38, and apply the division lemma to get

148 = 38 x 3 + 34

We consider the new divisor 38 and the new remainder 34,and apply the division lemma to get

38 = 34 x 1 + 4

We consider the new divisor 34 and the new remainder 4,and apply the division lemma to get

34 = 4 x 8 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 520 and 186 is 2

Notice that 2 = HCF(4,2) = HCF(34,4) = HCF(38,34) = HCF(148,38) = HCF(186,148) = HCF(520,186) .

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

Step 1: Since 518 > 2, we apply the division lemma to 518 and 2, to get

518 = 2 x 259 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 518 is 2

Notice that 2 = HCF(518,2) .
