HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 920, 589, 243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 920, 589, 243 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 920, 589, 243 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 920, 589, 243 is 1.

HCF(920, 589, 243) = 1

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

HCF of:

Highest common factor (HCF) of 920, 589, 243 is 1.

Highest Common Factor of 920,589,243 using Euclid's algorithm

Highest Common Factor of 920,589,243 is 1

Step 1: Since 920 > 589, we apply the division lemma to 920 and 589, to get

920 = 589 x 1 + 331

Step 2: Since the reminder 589 ≠ 0, we apply division lemma to 331 and 589, to get

589 = 331 x 1 + 258

Step 3: We consider the new divisor 331 and the new remainder 258, and apply the division lemma to get

331 = 258 x 1 + 73

We consider the new divisor 258 and the new remainder 73,and apply the division lemma to get

258 = 73 x 3 + 39

We consider the new divisor 73 and the new remainder 39,and apply the division lemma to get

73 = 39 x 1 + 34

We consider the new divisor 39 and the new remainder 34,and apply the division lemma to get

39 = 34 x 1 + 5

We consider the new divisor 34 and the new remainder 5,and apply the division lemma to get

34 = 5 x 6 + 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 920 and 589 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(34,5) = HCF(39,34) = HCF(73,39) = HCF(258,73) = HCF(331,258) = HCF(589,331) = HCF(920,589) .

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

Step 1: Since 243 > 1, we apply the division lemma to 243 and 1, to get

243 = 1 x 243 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 243 is 1

Notice that 1 = HCF(243,1) .
