HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 389, 587 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 389, 587 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, 587 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, 587 is 1.
HCF(389, 587) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 389, 587 is 1.
Step 1: Since 587 > 389, we apply the division lemma to 587 and 389, to get
587 = 389 x 1 + 198
Step 2: Since the reminder 389 ≠ 0, we apply division lemma to 198 and 389, to get
389 = 198 x 1 + 191
Step 3: We consider the new divisor 198 and the new remainder 191, and apply the division lemma to get
198 = 191 x 1 + 7
We consider the new divisor 191 and the new remainder 7,and apply the division lemma to get
191 = 7 x 27 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 389 and 587 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(191,7) = HCF(198,191) = HCF(389,198) = HCF(587,389) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 389, 587?
Answer: HCF of 389, 587 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 389, 587 using Euclid's Algorithm?
Answer: For arbitrary numbers 389, 587 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
