HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 796, 581, 742 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 796, 581, 742 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 796, 581, 742 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 796, 581, 742 is 1.

HCF(796, 581, 742) = 1

Highest common factor (HCF) of 796, 581, 742 is 1.

Highest Common Factor of 796,581,742 using Euclid's algorithm

Highest Common Factor of 796,581,742 is 1

Step 1: Since 796 > 581, we apply the division lemma to 796 and 581, to get

796 = 581 x 1 + 215

Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 215 and 581, to get

581 = 215 x 2 + 151

Step 3: We consider the new divisor 215 and the new remainder 151, and apply the division lemma to get

215 = 151 x 1 + 64

We consider the new divisor 151 and the new remainder 64,and apply the division lemma to get

151 = 64 x 2 + 23

We consider the new divisor 64 and the new remainder 23,and apply the division lemma to get

64 = 23 x 2 + 18

We consider the new divisor 23 and the new remainder 18,and apply the division lemma to get

23 = 18 x 1 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 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 796 and 581 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(23,18) = HCF(64,23) = HCF(151,64) = HCF(215,151) = HCF(581,215) = HCF(796,581) .

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

Step 1: Since 742 > 1, we apply the division lemma to 742 and 1, to get

742 = 1 x 742 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 742 is 1

Notice that 1 = HCF(742,1) .
