HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 729, 398, 543 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 729, 398, 543 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 729, 398, 543 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 729, 398, 543 is 1.

HCF(729, 398, 543) = 1

HCF of 729, 398, 543 using Euclid's algorithm

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

Highest common factor (HCF) of 729, 398, 543 is 1.

Highest Common Factor of 729,398,543 using Euclid's algorithm

Highest Common Factor of 729,398,543 is 1

Step 1: Since 729 > 398, we apply the division lemma to 729 and 398, to get

729 = 398 x 1 + 331

Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 331 and 398, to get

398 = 331 x 1 + 67

Step 3: We consider the new divisor 331 and the new remainder 67, and apply the division lemma to get

331 = 67 x 4 + 63

We consider the new divisor 67 and the new remainder 63,and apply the division lemma to get

67 = 63 x 1 + 4

We consider the new divisor 63 and the new remainder 4,and apply the division lemma to get

63 = 4 x 15 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 729 and 398 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(63,4) = HCF(67,63) = HCF(331,67) = HCF(398,331) = HCF(729,398) .

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

Step 1: Since 543 > 1, we apply the division lemma to 543 and 1, to get

543 = 1 x 543 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 543 is 1

Notice that 1 = HCF(543,1) .
