HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 323, 511, 197 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 323, 511, 197 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 323, 511, 197 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 323, 511, 197 is 1.

HCF(323, 511, 197) = 1

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

HCF of:

Highest common factor (HCF) of 323, 511, 197 is 1.

Highest Common Factor of 323,511,197 using Euclid's algorithm

Highest Common Factor of 323,511,197 is 1

Step 1: Since 511 > 323, we apply the division lemma to 511 and 323, to get

511 = 323 x 1 + 188

Step 2: Since the reminder 323 ≠ 0, we apply division lemma to 188 and 323, to get

323 = 188 x 1 + 135

Step 3: We consider the new divisor 188 and the new remainder 135, and apply the division lemma to get

188 = 135 x 1 + 53

We consider the new divisor 135 and the new remainder 53,and apply the division lemma to get

135 = 53 x 2 + 29

We consider the new divisor 53 and the new remainder 29,and apply the division lemma to get

53 = 29 x 1 + 24

We consider the new divisor 29 and the new remainder 24,and apply the division lemma to get

29 = 24 x 1 + 5

We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get

24 = 5 x 4 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 323 and 511 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(53,29) = HCF(135,53) = HCF(188,135) = HCF(323,188) = HCF(511,323) .

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

Step 1: Since 197 > 1, we apply the division lemma to 197 and 1, to get

197 = 1 x 197 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 197 is 1

Notice that 1 = HCF(197,1) .
