HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 995, 591, 709 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 995, 591, 709 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 995, 591, 709 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 995, 591, 709 is 1.
HCF(995, 591, 709) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 995, 591, 709 is 1.
Step 1: Since 995 > 591, we apply the division lemma to 995 and 591, to get
995 = 591 x 1 + 404
Step 2: Since the reminder 591 ≠ 0, we apply division lemma to 404 and 591, to get
591 = 404 x 1 + 187
Step 3: We consider the new divisor 404 and the new remainder 187, and apply the division lemma to get
404 = 187 x 2 + 30
We consider the new divisor 187 and the new remainder 30,and apply the division lemma to get
187 = 30 x 6 + 7
We consider the new divisor 30 and the new remainder 7,and apply the division lemma to get
30 = 7 x 4 + 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 995 and 591 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(30,7) = HCF(187,30) = HCF(404,187) = HCF(591,404) = HCF(995,591) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 709 > 1, we apply the division lemma to 709 and 1, to get
709 = 1 x 709 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 709 is 1
Notice that 1 = HCF(709,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 995, 591, 709?
Answer: HCF of 995, 591, 709 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 995, 591, 709 using Euclid's Algorithm?
Answer: For arbitrary numbers 995, 591, 709 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
