HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 444, 343, 404 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 444, 343, 404 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 444, 343, 404 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 444, 343, 404 is 1.
HCF(444, 343, 404) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 444, 343, 404 is 1.
Step 1: Since 444 > 343, we apply the division lemma to 444 and 343, to get
444 = 343 x 1 + 101
Step 2: Since the reminder 343 ≠ 0, we apply division lemma to 101 and 343, to get
343 = 101 x 3 + 40
Step 3: We consider the new divisor 101 and the new remainder 40, and apply the division lemma to get
101 = 40 x 2 + 21
We consider the new divisor 40 and the new remainder 21,and apply the division lemma to get
40 = 21 x 1 + 19
We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get
21 = 19 x 1 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 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 444 and 343 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(40,21) = HCF(101,40) = HCF(343,101) = HCF(444,343) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 404 > 1, we apply the division lemma to 404 and 1, to get
404 = 1 x 404 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 404 is 1
Notice that 1 = HCF(404,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 444, 343, 404?
Answer: HCF of 444, 343, 404 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 444, 343, 404 using Euclid's Algorithm?
Answer: For arbitrary numbers 444, 343, 404 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
