HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 943 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 581, 943 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, 943 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, 943 is 1.

HCF(581, 943) = 1

Highest common factor (HCF) of 581, 943 is 1.

Highest Common Factor of 581,943 using Euclid's algorithm

Highest Common Factor of 581,943 is 1

Step 1: Since 943 > 581, we apply the division lemma to 943 and 581, to get

943 = 581 x 1 + 362

Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 362 and 581, to get

581 = 362 x 1 + 219

Step 3: We consider the new divisor 362 and the new remainder 219, and apply the division lemma to get

362 = 219 x 1 + 143

We consider the new divisor 219 and the new remainder 143,and apply the division lemma to get

219 = 143 x 1 + 76

We consider the new divisor 143 and the new remainder 76,and apply the division lemma to get

143 = 76 x 1 + 67

We consider the new divisor 76 and the new remainder 67,and apply the division lemma to get

76 = 67 x 1 + 9

We consider the new divisor 67 and the new remainder 9,and apply the division lemma to get

67 = 9 x 7 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 943 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(67,9) = HCF(76,67) = HCF(143,76) = HCF(219,143) = HCF(362,219) = HCF(581,362) = HCF(943,581) .
