HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 804, 215 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 571, 804, 215 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 571, 804, 215 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 571, 804, 215 is 1.

HCF(571, 804, 215) = 1

HCF of 571, 804, 215 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 571, 804, 215 is 1.

Highest Common Factor of 571,804,215 using Euclid's algorithm

Highest Common Factor of 571,804,215 is 1

Step 1: Since 804 > 571, we apply the division lemma to 804 and 571, to get

804 = 571 x 1 + 233

Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 233 and 571, to get

571 = 233 x 2 + 105

Step 3: We consider the new divisor 233 and the new remainder 105, and apply the division lemma to get

233 = 105 x 2 + 23

We consider the new divisor 105 and the new remainder 23,and apply the division lemma to get

105 = 23 x 4 + 13

We consider the new divisor 23 and the new remainder 13,and apply the division lemma to get

23 = 13 x 1 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 571 and 804 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(23,13) = HCF(105,23) = HCF(233,105) = HCF(571,233) = HCF(804,571) .


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

Step 1: Since 215 > 1, we apply the division lemma to 215 and 1, to get

215 = 1 x 215 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 215 is 1

Notice that 1 = HCF(215,1) .
