HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 572, 321, 849 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 572, 321, 849 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 572, 321, 849 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 572, 321, 849 is 1.

HCF(572, 321, 849) = 1

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

HCF of:

Highest common factor (HCF) of 572, 321, 849 is 1.

Highest Common Factor of 572,321,849 using Euclid's algorithm

Highest Common Factor of 572,321,849 is 1

Step 1: Since 572 > 321, we apply the division lemma to 572 and 321, to get

572 = 321 x 1 + 251

Step 2: Since the reminder 321 ≠ 0, we apply division lemma to 251 and 321, to get

321 = 251 x 1 + 70

Step 3: We consider the new divisor 251 and the new remainder 70, and apply the division lemma to get

251 = 70 x 3 + 41

We consider the new divisor 70 and the new remainder 41,and apply the division lemma to get

70 = 41 x 1 + 29

We consider the new divisor 41 and the new remainder 29,and apply the division lemma to get

41 = 29 x 1 + 12

We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get

29 = 12 x 2 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 572 and 321 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(41,29) = HCF(70,41) = HCF(251,70) = HCF(321,251) = HCF(572,321) .

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

Step 1: Since 849 > 1, we apply the division lemma to 849 and 1, to get

849 = 1 x 849 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 849 is 1

Notice that 1 = HCF(849,1) .
