HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 216, 868 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 404, 216, 868 is 4 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 404, 216, 868 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 404, 216, 868 is 4.
HCF(404, 216, 868) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 404, 216, 868 is 4.
Step 1: Since 404 > 216, we apply the division lemma to 404 and 216, to get
404 = 216 x 1 + 188
Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 188 and 216, to get
216 = 188 x 1 + 28
Step 3: We consider the new divisor 188 and the new remainder 28, and apply the division lemma to get
188 = 28 x 6 + 20
We consider the new divisor 28 and the new remainder 20,and apply the division lemma to get
28 = 20 x 1 + 8
We consider the new divisor 20 and the new remainder 8,and apply the division lemma to get
20 = 8 x 2 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 404 and 216 is 4
Notice that 4 = HCF(8,4) = HCF(20,8) = HCF(28,20) = HCF(188,28) = HCF(216,188) = HCF(404,216) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 868 > 4, we apply the division lemma to 868 and 4, to get
868 = 4 x 217 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 868 is 4
Notice that 4 = HCF(868,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 404, 216, 868?
Answer: HCF of 404, 216, 868 is 4 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 404, 216, 868 using Euclid's Algorithm?
Answer: For arbitrary numbers 404, 216, 868 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
