HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9831, 6805, 90585 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 9831, 6805, 90585 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 9831, 6805, 90585 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 9831, 6805, 90585 is 1.

HCF(9831, 6805, 90585) = 1

HCF of 9831, 6805, 90585 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 9831, 6805, 90585 is 1.

Highest Common Factor of 9831,6805,90585 using Euclid's algorithm

Highest Common Factor of 9831,6805,90585 is 1

Step 1: Since 9831 > 6805, we apply the division lemma to 9831 and 6805, to get

9831 = 6805 x 1 + 3026

Step 2: Since the reminder 6805 ≠ 0, we apply division lemma to 3026 and 6805, to get

6805 = 3026 x 2 + 753

Step 3: We consider the new divisor 3026 and the new remainder 753, and apply the division lemma to get

3026 = 753 x 4 + 14

We consider the new divisor 753 and the new remainder 14,and apply the division lemma to get

753 = 14 x 53 + 11

We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get

14 = 11 x 1 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 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 9831 and 6805 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(753,14) = HCF(3026,753) = HCF(6805,3026) = HCF(9831,6805) .

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

Step 1: Since 90585 > 1, we apply the division lemma to 90585 and 1, to get

90585 = 1 x 90585 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 90585 is 1

Notice that 1 = HCF(90585,1) .
