HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 992, 581 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 992, 581 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 992, 581 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 992, 581 is 1.

HCF(992, 581) = 1

Highest common factor (HCF) of 992, 581 is 1.

Highest Common Factor of 992,581 using Euclid's algorithm

Highest Common Factor of 992,581 is 1

Step 1: Since 992 > 581, we apply the division lemma to 992 and 581, to get

992 = 581 x 1 + 411

Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 411 and 581, to get

581 = 411 x 1 + 170

Step 3: We consider the new divisor 411 and the new remainder 170, and apply the division lemma to get

411 = 170 x 2 + 71

We consider the new divisor 170 and the new remainder 71,and apply the division lemma to get

170 = 71 x 2 + 28

We consider the new divisor 71 and the new remainder 28,and apply the division lemma to get

71 = 28 x 2 + 15

We consider the new divisor 28 and the new remainder 15,and apply the division lemma to get

28 = 15 x 1 + 13

We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 992 and 581 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(71,28) = HCF(170,71) = HCF(411,170) = HCF(581,411) = HCF(992,581) .
