HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 581, 481 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, 481 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, 481 is 1.

HCF(581, 481) = 1

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

HCF of:

Highest common factor (HCF) of 581, 481 is 1.

Highest Common Factor of 581,481 using Euclid's algorithm

Highest Common Factor of 581,481 is 1

Step 1: Since 581 > 481, we apply the division lemma to 581 and 481, to get

581 = 481 x 1 + 100

Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 100 and 481, to get

481 = 100 x 4 + 81

Step 3: We consider the new divisor 100 and the new remainder 81, and apply the division lemma to get

100 = 81 x 1 + 19

We consider the new divisor 81 and the new remainder 19,and apply the division lemma to get

81 = 19 x 4 + 5

We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get

19 = 5 x 3 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 581 and 481 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(81,19) = HCF(100,81) = HCF(481,100) = HCF(581,481) .
