HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 564, 831, 389 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 564, 831, 389 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 564, 831, 389 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 564, 831, 389 is 1.

HCF(564, 831, 389) = 1

HCF of 564, 831, 389 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 564, 831, 389 is 1.

Highest Common Factor of 564,831,389 using Euclid's algorithm

Highest Common Factor of 564,831,389 is 1

Step 1: Since 831 > 564, we apply the division lemma to 831 and 564, to get

831 = 564 x 1 + 267

Step 2: Since the reminder 564 ≠ 0, we apply division lemma to 267 and 564, to get

564 = 267 x 2 + 30

Step 3: We consider the new divisor 267 and the new remainder 30, and apply the division lemma to get

267 = 30 x 8 + 27

We consider the new divisor 30 and the new remainder 27,and apply the division lemma to get

30 = 27 x 1 + 3

We consider the new divisor 27 and the new remainder 3,and apply the division lemma to get

27 = 3 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 564 and 831 is 3

Notice that 3 = HCF(27,3) = HCF(30,27) = HCF(267,30) = HCF(564,267) = HCF(831,564) .

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

Step 1: Since 389 > 3, we apply the division lemma to 389 and 3, to get

389 = 3 x 129 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 389 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(389,3) .
