HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 804, 831, 479 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 804, 831, 479 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 804, 831, 479 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 804, 831, 479 is 1.

HCF(804, 831, 479) = 1

HCF of 804, 831, 479 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 804, 831, 479 is 1.

Highest Common Factor of 804,831,479 using Euclid's algorithm

Highest Common Factor of 804,831,479 is 1

Step 1: Since 831 > 804, we apply the division lemma to 831 and 804, to get

831 = 804 x 1 + 27

Step 2: Since the reminder 804 ≠ 0, we apply division lemma to 27 and 804, to get

804 = 27 x 29 + 21

Step 3: We consider the new divisor 27 and the new remainder 21, and apply the division lemma to get

27 = 21 x 1 + 6

We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get

21 = 6 x 3 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 804 and 831 is 3

Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(27,21) = HCF(804,27) = HCF(831,804) .

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

Step 1: Since 479 > 3, we apply the division lemma to 479 and 3, to get

479 = 3 x 159 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 479 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(479,3) .
