HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 399, 311, 729 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 399, 311, 729 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 399, 311, 729 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 399, 311, 729 is 1.

HCF(399, 311, 729) = 1

Highest common factor (HCF) of 399, 311, 729 is 1.

Highest Common Factor of 399,311,729 using Euclid's algorithm

Highest Common Factor of 399,311,729 is 1

Step 1: Since 399 > 311, we apply the division lemma to 399 and 311, to get

399 = 311 x 1 + 88

Step 2: Since the reminder 311 ≠ 0, we apply division lemma to 88 and 311, to get

311 = 88 x 3 + 47

Step 3: We consider the new divisor 88 and the new remainder 47, and apply the division lemma to get

88 = 47 x 1 + 41

We consider the new divisor 47 and the new remainder 41,and apply the division lemma to get

47 = 41 x 1 + 6

We consider the new divisor 41 and the new remainder 6,and apply the division lemma to get

41 = 6 x 6 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 399 and 311 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(41,6) = HCF(47,41) = HCF(88,47) = HCF(311,88) = HCF(399,311) .

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

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

729 = 1 x 729 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 729 is 1

Notice that 1 = HCF(729,1) .
