HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 394, 621, 589 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 394, 621, 589 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 394, 621, 589 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 394, 621, 589 is 1.

HCF(394, 621, 589) = 1

Highest common factor (HCF) of 394, 621, 589 is 1.

Highest Common Factor of 394,621,589 using Euclid's algorithm

Highest Common Factor of 394,621,589 is 1

Step 1: Since 621 > 394, we apply the division lemma to 621 and 394, to get

621 = 394 x 1 + 227

Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 227 and 394, to get

394 = 227 x 1 + 167

Step 3: We consider the new divisor 227 and the new remainder 167, and apply the division lemma to get

227 = 167 x 1 + 60

We consider the new divisor 167 and the new remainder 60,and apply the division lemma to get

167 = 60 x 2 + 47

We consider the new divisor 60 and the new remainder 47,and apply the division lemma to get

60 = 47 x 1 + 13

We consider the new divisor 47 and the new remainder 13,and apply the division lemma to get

47 = 13 x 3 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 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 394 and 621 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(47,13) = HCF(60,47) = HCF(167,60) = HCF(227,167) = HCF(394,227) = HCF(621,394) .

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

Step 1: Since 589 > 1, we apply the division lemma to 589 and 1, to get

589 = 1 x 589 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 589 is 1

Notice that 1 = HCF(589,1) .
