HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 679, 489, 804 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 679, 489, 804 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 679, 489, 804 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 679, 489, 804 is 1.

HCF(679, 489, 804) = 1

HCF of 679, 489, 804 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 679, 489, 804 is 1.

Highest Common Factor of 679,489,804 using Euclid's algorithm

Highest Common Factor of 679,489,804 is 1

Step 1: Since 679 > 489, we apply the division lemma to 679 and 489, to get

679 = 489 x 1 + 190

Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 190 and 489, to get

489 = 190 x 2 + 109

Step 3: We consider the new divisor 190 and the new remainder 109, and apply the division lemma to get

190 = 109 x 1 + 81

We consider the new divisor 109 and the new remainder 81,and apply the division lemma to get

109 = 81 x 1 + 28

We consider the new divisor 81 and the new remainder 28,and apply the division lemma to get

81 = 28 x 2 + 25

We consider the new divisor 28 and the new remainder 25,and apply the division lemma to get

28 = 25 x 1 + 3

We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get

25 = 3 x 8 + 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 679 and 489 is 1

Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(28,25) = HCF(81,28) = HCF(109,81) = HCF(190,109) = HCF(489,190) = HCF(679,489) .

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

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

804 = 1 x 804 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 804 is 1

Notice that 1 = HCF(804,1) .
