HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 632, 393 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 811, 632, 393 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 811, 632, 393 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 811, 632, 393 is 1.
HCF(811, 632, 393) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 811, 632, 393 is 1.
Step 1: Since 811 > 632, we apply the division lemma to 811 and 632, to get
811 = 632 x 1 + 179
Step 2: Since the reminder 632 ≠ 0, we apply division lemma to 179 and 632, to get
632 = 179 x 3 + 95
Step 3: We consider the new divisor 179 and the new remainder 95, and apply the division lemma to get
179 = 95 x 1 + 84
We consider the new divisor 95 and the new remainder 84,and apply the division lemma to get
95 = 84 x 1 + 11
We consider the new divisor 84 and the new remainder 11,and apply the division lemma to get
84 = 11 x 7 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 811 and 632 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(84,11) = HCF(95,84) = HCF(179,95) = HCF(632,179) = HCF(811,632) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 393 > 1, we apply the division lemma to 393 and 1, to get
393 = 1 x 393 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 393 is 1
Notice that 1 = HCF(393,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 811, 632, 393?
Answer: HCF of 811, 632, 393 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 811, 632, 393 using Euclid's Algorithm?
Answer: For arbitrary numbers 811, 632, 393 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
