HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 873, 409 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 520, 873, 409 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 520, 873, 409 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, 873, 409 is 1.

HCF(520, 873, 409) = 1

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

HCF of:

Highest common factor (HCF) of 520, 873, 409 is 1.

Highest Common Factor of 520,873,409 using Euclid's algorithm

Highest Common Factor of 520,873,409 is 1

Step 1: Since 873 > 520, we apply the division lemma to 873 and 520, to get

873 = 520 x 1 + 353

Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 353 and 520, to get

520 = 353 x 1 + 167

Step 3: We consider the new divisor 353 and the new remainder 167, and apply the division lemma to get

353 = 167 x 2 + 19

We consider the new divisor 167 and the new remainder 19,and apply the division lemma to get

167 = 19 x 8 + 15

We consider the new divisor 19 and the new remainder 15,and apply the division lemma to get

19 = 15 x 1 + 4

We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get

15 = 4 x 3 + 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 520 and 873 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(19,15) = HCF(167,19) = HCF(353,167) = HCF(520,353) = HCF(873,520) .

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

Step 1: Since 409 > 1, we apply the division lemma to 409 and 1, to get

409 = 1 x 409 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 409 is 1

Notice that 1 = HCF(409,1) .
