HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 301, 806, 489 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 301, 806, 489 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 301, 806, 489 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 301, 806, 489 is 1.
HCF(301, 806, 489) = 1
HCF of 301, 806, 489 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 301, 806, 489 is 1.
Highest Common Factor of 301,806,489 is 1
Step 1: Since 806 > 301, we apply the division lemma to 806 and 301, to get
806 = 301 x 2 + 204
Step 2: Since the reminder 301 ≠ 0, we apply division lemma to 204 and 301, to get
301 = 204 x 1 + 97
Step 3: We consider the new divisor 204 and the new remainder 97, and apply the division lemma to get
204 = 97 x 2 + 10
We consider the new divisor 97 and the new remainder 10,and apply the division lemma to get
97 = 10 x 9 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 301 and 806 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(97,10) = HCF(204,97) = HCF(301,204) = HCF(806,301) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 489 > 1, we apply the division lemma to 489 and 1, to get
489 = 1 x 489 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 489 is 1
Notice that 1 = HCF(489,1) .
