HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 311, 184, 816 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 311, 184, 816 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 311, 184, 816 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 311, 184, 816 is 1.
HCF(311, 184, 816) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 311, 184, 816 is 1.
Step 1: Since 311 > 184, we apply the division lemma to 311 and 184, to get
311 = 184 x 1 + 127
Step 2: Since the reminder 184 ≠ 0, we apply division lemma to 127 and 184, to get
184 = 127 x 1 + 57
Step 3: We consider the new divisor 127 and the new remainder 57, and apply the division lemma to get
127 = 57 x 2 + 13
We consider the new divisor 57 and the new remainder 13,and apply the division lemma to get
57 = 13 x 4 + 5
We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get
13 = 5 x 2 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 311 and 184 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(57,13) = HCF(127,57) = HCF(184,127) = HCF(311,184) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 816 > 1, we apply the division lemma to 816 and 1, to get
816 = 1 x 816 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 816 is 1
Notice that 1 = HCF(816,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 311, 184, 816?
Answer: HCF of 311, 184, 816 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 311, 184, 816 using Euclid's Algorithm?
Answer: For arbitrary numbers 311, 184, 816 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
