HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 720, 511 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 581, 720, 511 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 581, 720, 511 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 581, 720, 511 is 1.

HCF(581, 720, 511) = 1

Highest common factor (HCF) of 581, 720, 511 is 1.

Highest Common Factor of 581,720,511 using Euclid's algorithm

Highest Common Factor of 581,720,511 is 1

Step 1: Since 720 > 581, we apply the division lemma to 720 and 581, to get

720 = 581 x 1 + 139

Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 139 and 581, to get

581 = 139 x 4 + 25

Step 3: We consider the new divisor 139 and the new remainder 25, and apply the division lemma to get

139 = 25 x 5 + 14

We consider the new divisor 25 and the new remainder 14,and apply the division lemma to get

25 = 14 x 1 + 11

We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get

14 = 11 x 1 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 581 and 720 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(25,14) = HCF(139,25) = HCF(581,139) = HCF(720,581) .


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

Step 1: Since 511 > 1, we apply the division lemma to 511 and 1, to get

511 = 1 x 511 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 511 is 1

Notice that 1 = HCF(511,1) .
