HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 503, 580, 815 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 503, 580, 815 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 503, 580, 815 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 503, 580, 815 is 1.

HCF(503, 580, 815) = 1

Highest common factor (HCF) of 503, 580, 815 is 1.

Highest Common Factor of 503,580,815 using Euclid's algorithm

Highest Common Factor of 503,580,815 is 1

Step 1: Since 580 > 503, we apply the division lemma to 580 and 503, to get

580 = 503 x 1 + 77

Step 2: Since the reminder 503 ≠ 0, we apply division lemma to 77 and 503, to get

503 = 77 x 6 + 41

Step 3: We consider the new divisor 77 and the new remainder 41, and apply the division lemma to get

77 = 41 x 1 + 36

We consider the new divisor 41 and the new remainder 36,and apply the division lemma to get

41 = 36 x 1 + 5

We consider the new divisor 36 and the new remainder 5,and apply the division lemma to get

36 = 5 x 7 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 503 and 580 is 1

Notice that 1 = HCF(5,1) = HCF(36,5) = HCF(41,36) = HCF(77,41) = HCF(503,77) = HCF(580,503) .

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

Step 1: Since 815 > 1, we apply the division lemma to 815 and 1, to get

815 = 1 x 815 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 815 is 1

Notice that 1 = HCF(815,1) .
