HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 191, 539, 873 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 191, 539, 873 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 191, 539, 873 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 191, 539, 873 is 1.

HCF(191, 539, 873) = 1

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

HCF of:

Highest common factor (HCF) of 191, 539, 873 is 1.

Highest Common Factor of 191,539,873 using Euclid's algorithm

Highest Common Factor of 191,539,873 is 1

Step 1: Since 539 > 191, we apply the division lemma to 539 and 191, to get

539 = 191 x 2 + 157

Step 2: Since the reminder 191 ≠ 0, we apply division lemma to 157 and 191, to get

191 = 157 x 1 + 34

Step 3: We consider the new divisor 157 and the new remainder 34, and apply the division lemma to get

157 = 34 x 4 + 21

We consider the new divisor 34 and the new remainder 21,and apply the division lemma to get

34 = 21 x 1 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 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 191 and 539 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(34,21) = HCF(157,34) = HCF(191,157) = HCF(539,191) .

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

Step 1: Since 873 > 1, we apply the division lemma to 873 and 1, to get

873 = 1 x 873 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 873 is 1

Notice that 1 = HCF(873,1) .
