HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 387, 564 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 857, 387, 564 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 857, 387, 564 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 857, 387, 564 is 1.

HCF(857, 387, 564) = 1

HCF of 857, 387, 564 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 857, 387, 564 is 1.

Highest Common Factor of 857,387,564 using Euclid's algorithm

Highest Common Factor of 857,387,564 is 1

Step 1: Since 857 > 387, we apply the division lemma to 857 and 387, to get

857 = 387 x 2 + 83

Step 2: Since the reminder 387 ≠ 0, we apply division lemma to 83 and 387, to get

387 = 83 x 4 + 55

Step 3: We consider the new divisor 83 and the new remainder 55, and apply the division lemma to get

83 = 55 x 1 + 28

We consider the new divisor 55 and the new remainder 28,and apply the division lemma to get

55 = 28 x 1 + 27

We consider the new divisor 28 and the new remainder 27,and apply the division lemma to get

28 = 27 x 1 + 1

We consider the new divisor 27 and the new remainder 1,and apply the division lemma to get

27 = 1 x 27 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 857 and 387 is 1

Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(55,28) = HCF(83,55) = HCF(387,83) = HCF(857,387) .

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

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

564 = 1 x 564 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 564 is 1

Notice that 1 = HCF(564,1) .
