HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 580, 817 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 870, 580, 817 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 870, 580, 817 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 870, 580, 817 is 1.

HCF(870, 580, 817) = 1

Highest common factor (HCF) of 870, 580, 817 is 1.

Highest Common Factor of 870,580,817 using Euclid's algorithm

Highest Common Factor of 870,580,817 is 1

Step 1: Since 870 > 580, we apply the division lemma to 870 and 580, to get

870 = 580 x 1 + 290

Step 2: Since the reminder 580 ≠ 0, we apply division lemma to 290 and 580, to get

580 = 290 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 290, the HCF of 870 and 580 is 290

Notice that 290 = HCF(580,290) = HCF(870,580) .

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

Step 1: Since 817 > 290, we apply the division lemma to 817 and 290, to get

817 = 290 x 2 + 237

Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 237 and 290, to get

290 = 237 x 1 + 53

Step 3: We consider the new divisor 237 and the new remainder 53, and apply the division lemma to get

237 = 53 x 4 + 25

We consider the new divisor 53 and the new remainder 25,and apply the division lemma to get

53 = 25 x 2 + 3

We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get

25 = 3 x 8 + 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 290 and 817 is 1

Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(53,25) = HCF(237,53) = HCF(290,237) = HCF(817,290) .
