HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 389, 300, 449 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 389, 300, 449 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 389, 300, 449 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 389, 300, 449 is 1.
HCF(389, 300, 449) = 1
HCF of 389, 300, 449 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 389, 300, 449 is 1.
Highest Common Factor of 389,300,449 is 1
Step 1: Since 389 > 300, we apply the division lemma to 389 and 300, to get
389 = 300 x 1 + 89
Step 2: Since the reminder 300 ≠ 0, we apply division lemma to 89 and 300, to get
300 = 89 x 3 + 33
Step 3: We consider the new divisor 89 and the new remainder 33, and apply the division lemma to get
89 = 33 x 2 + 23
We consider the new divisor 33 and the new remainder 23,and apply the division lemma to get
33 = 23 x 1 + 10
We consider the new divisor 23 and the new remainder 10,and apply the division lemma to get
23 = 10 x 2 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 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 389 and 300 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(33,23) = HCF(89,33) = HCF(300,89) = HCF(389,300) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 449 > 1, we apply the division lemma to 449 and 1, to get
449 = 1 x 449 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 449 is 1
Notice that 1 = HCF(449,1) .
