HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 368, 971 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 831, 368, 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 831, 368, 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 831, 368, 971 is 1.
HCF(831, 368, 971) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 831, 368, 971 is 1.
Step 1: Since 831 > 368, we apply the division lemma to 831 and 368, to get
831 = 368 x 2 + 95
Step 2: Since the reminder 368 ≠ 0, we apply division lemma to 95 and 368, to get
368 = 95 x 3 + 83
Step 3: We consider the new divisor 95 and the new remainder 83, and apply the division lemma to get
95 = 83 x 1 + 12
We consider the new divisor 83 and the new remainder 12,and apply the division lemma to get
83 = 12 x 6 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 831 and 368 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(83,12) = HCF(95,83) = HCF(368,95) = HCF(831,368) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 971 > 1, we apply the division lemma to 971 and 1, to get
971 = 1 x 971 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 971 is 1
Notice that 1 = HCF(971,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 831, 368, 971?
Answer: HCF of 831, 368, 971 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 831, 368, 971 using Euclid's Algorithm?
Answer: For arbitrary numbers 831, 368, 971 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
