HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 871, 235, 318 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 871, 235, 318 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 871, 235, 318 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 871, 235, 318 is 1.
HCF(871, 235, 318) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 871, 235, 318 is 1.
Step 1: Since 871 > 235, we apply the division lemma to 871 and 235, to get
871 = 235 x 3 + 166
Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 166 and 235, to get
235 = 166 x 1 + 69
Step 3: We consider the new divisor 166 and the new remainder 69, and apply the division lemma to get
166 = 69 x 2 + 28
We consider the new divisor 69 and the new remainder 28,and apply the division lemma to get
69 = 28 x 2 + 13
We consider the new divisor 28 and the new remainder 13,and apply the division lemma to get
28 = 13 x 2 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 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 871 and 235 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(28,13) = HCF(69,28) = HCF(166,69) = HCF(235,166) = HCF(871,235) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 318 > 1, we apply the division lemma to 318 and 1, to get
318 = 1 x 318 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 318 is 1
Notice that 1 = HCF(318,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 871, 235, 318?
Answer: HCF of 871, 235, 318 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 871, 235, 318 using Euclid's Algorithm?
Answer: For arbitrary numbers 871, 235, 318 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
