HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 530, 817, 355 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 530, 817, 355 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 530, 817, 355 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 530, 817, 355 is 1.

HCF(530, 817, 355) = 1

HCF of 530, 817, 355 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 530, 817, 355 is 1.

Highest Common Factor of 530,817,355 using Euclid's algorithm

Highest Common Factor of 530,817,355 is 1

Step 1: Since 817 > 530, we apply the division lemma to 817 and 530, to get

817 = 530 x 1 + 287

Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 287 and 530, to get

530 = 287 x 1 + 243

Step 3: We consider the new divisor 287 and the new remainder 243, and apply the division lemma to get

287 = 243 x 1 + 44

We consider the new divisor 243 and the new remainder 44,and apply the division lemma to get

243 = 44 x 5 + 23

We consider the new divisor 44 and the new remainder 23,and apply the division lemma to get

44 = 23 x 1 + 21

We consider the new divisor 23 and the new remainder 21,and apply the division lemma to get

23 = 21 x 1 + 2

We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get

21 = 2 x 10 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 530 and 817 is 1

Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(23,21) = HCF(44,23) = HCF(243,44) = HCF(287,243) = HCF(530,287) = HCF(817,530) .


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

Step 1: Since 355 > 1, we apply the division lemma to 355 and 1, to get

355 = 1 x 355 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 355 is 1

Notice that 1 = HCF(355,1) .
