HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 377 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 581, 377 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, 377 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, 377 is 1.

HCF(581, 377) = 1

Highest common factor (HCF) of 581, 377 is 1.

Highest Common Factor of 581,377 using Euclid's algorithm

Highest Common Factor of 581,377 is 1

Step 1: Since 581 > 377, we apply the division lemma to 581 and 377, to get

581 = 377 x 1 + 204

Step 2: Since the reminder 377 ≠ 0, we apply division lemma to 204 and 377, to get

377 = 204 x 1 + 173

Step 3: We consider the new divisor 204 and the new remainder 173, and apply the division lemma to get

204 = 173 x 1 + 31

We consider the new divisor 173 and the new remainder 31,and apply the division lemma to get

173 = 31 x 5 + 18

We consider the new divisor 31 and the new remainder 18,and apply the division lemma to get

31 = 18 x 1 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 377 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(31,18) = HCF(173,31) = HCF(204,173) = HCF(377,204) = HCF(581,377) .
