HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 396, 571, 345 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 396, 571, 345 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 396, 571, 345 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 396, 571, 345 is 1.
HCF(396, 571, 345) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 396, 571, 345 is 1.
Step 1: Since 571 > 396, we apply the division lemma to 571 and 396, to get
571 = 396 x 1 + 175
Step 2: Since the reminder 396 ≠ 0, we apply division lemma to 175 and 396, to get
396 = 175 x 2 + 46
Step 3: We consider the new divisor 175 and the new remainder 46, and apply the division lemma to get
175 = 46 x 3 + 37
We consider the new divisor 46 and the new remainder 37,and apply the division lemma to get
46 = 37 x 1 + 9
We consider the new divisor 37 and the new remainder 9,and apply the division lemma to get
37 = 9 x 4 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 396 and 571 is 1
Notice that 1 = HCF(9,1) = HCF(37,9) = HCF(46,37) = HCF(175,46) = HCF(396,175) = HCF(571,396) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 345 > 1, we apply the division lemma to 345 and 1, to get
345 = 1 x 345 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 345 is 1
Notice that 1 = HCF(345,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 396, 571, 345?
Answer: HCF of 396, 571, 345 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 396, 571, 345 using Euclid's Algorithm?
Answer: For arbitrary numbers 396, 571, 345 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
