HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 971 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 971 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 797, 971 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 797, 971 is 1.
HCF(797, 971) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 797, 971 is 1.
Step 1: Since 971 > 797, we apply the division lemma to 971 and 797, to get
971 = 797 x 1 + 174
Step 2: Since the reminder 797 ≠ 0, we apply division lemma to 174 and 797, to get
797 = 174 x 4 + 101
Step 3: We consider the new divisor 174 and the new remainder 101, and apply the division lemma to get
174 = 101 x 1 + 73
We consider the new divisor 101 and the new remainder 73,and apply the division lemma to get
101 = 73 x 1 + 28
We consider the new divisor 73 and the new remainder 28,and apply the division lemma to get
73 = 28 x 2 + 17
We consider the new divisor 28 and the new remainder 17,and apply the division lemma to get
28 = 17 x 1 + 11
We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 797 and 971 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(28,17) = HCF(73,28) = HCF(101,73) = HCF(174,101) = HCF(797,174) = HCF(971,797) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 797, 971?
Answer: HCF of 797, 971 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 797, 971 using Euclid's Algorithm?
Answer: For arbitrary numbers 797, 971 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
