HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 371, 414 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 581, 371, 414 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 581, 371, 414 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 581, 371, 414 is 1.
HCF(581, 371, 414) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 581, 371, 414 is 1.
Step 1: Since 581 > 371, we apply the division lemma to 581 and 371, to get
581 = 371 x 1 + 210
Step 2: Since the reminder 371 ≠ 0, we apply division lemma to 210 and 371, to get
371 = 210 x 1 + 161
Step 3: We consider the new divisor 210 and the new remainder 161, and apply the division lemma to get
210 = 161 x 1 + 49
We consider the new divisor 161 and the new remainder 49,and apply the division lemma to get
161 = 49 x 3 + 14
We consider the new divisor 49 and the new remainder 14,and apply the division lemma to get
49 = 14 x 3 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 581 and 371 is 7
Notice that 7 = HCF(14,7) = HCF(49,14) = HCF(161,49) = HCF(210,161) = HCF(371,210) = HCF(581,371) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 414 > 7, we apply the division lemma to 414 and 7, to get
414 = 7 x 59 + 1
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 1 and 7, to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 414 is 1
Notice that 1 = HCF(7,1) = HCF(414,7) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 581, 371, 414?
Answer: HCF of 581, 371, 414 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 581, 371, 414 using Euclid's Algorithm?
Answer: For arbitrary numbers 581, 371, 414 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
