HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 315, 443 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 404, 315, 443 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 404, 315, 443 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, 315, 443 is 1.
HCF(404, 315, 443) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 404, 315, 443 is 1.
Step 1: Since 404 > 315, we apply the division lemma to 404 and 315, to get
404 = 315 x 1 + 89
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 89 and 315, to get
315 = 89 x 3 + 48
Step 3: We consider the new divisor 89 and the new remainder 48, and apply the division lemma to get
89 = 48 x 1 + 41
We consider the new divisor 48 and the new remainder 41,and apply the division lemma to get
48 = 41 x 1 + 7
We consider the new divisor 41 and the new remainder 7,and apply the division lemma to get
41 = 7 x 5 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 404 and 315 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(41,7) = HCF(48,41) = HCF(89,48) = HCF(315,89) = HCF(404,315) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 443 > 1, we apply the division lemma to 443 and 1, to get
443 = 1 x 443 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 443 is 1
Notice that 1 = HCF(443,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 404, 315, 443?
Answer: HCF of 404, 315, 443 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 404, 315, 443 using Euclid's Algorithm?
Answer: For arbitrary numbers 404, 315, 443 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
