HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 481, 306, 417 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 481, 306, 417 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 481, 306, 417 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 481, 306, 417 is 1.
HCF(481, 306, 417) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 481, 306, 417 is 1.
Step 1: Since 481 > 306, we apply the division lemma to 481 and 306, to get
481 = 306 x 1 + 175
Step 2: Since the reminder 306 ≠ 0, we apply division lemma to 175 and 306, to get
306 = 175 x 1 + 131
Step 3: We consider the new divisor 175 and the new remainder 131, and apply the division lemma to get
175 = 131 x 1 + 44
We consider the new divisor 131 and the new remainder 44,and apply the division lemma to get
131 = 44 x 2 + 43
We consider the new divisor 44 and the new remainder 43,and apply the division lemma to get
44 = 43 x 1 + 1
We consider the new divisor 43 and the new remainder 1,and apply the division lemma to get
43 = 1 x 43 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 481 and 306 is 1
Notice that 1 = HCF(43,1) = HCF(44,43) = HCF(131,44) = HCF(175,131) = HCF(306,175) = HCF(481,306) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 417 > 1, we apply the division lemma to 417 and 1, to get
417 = 1 x 417 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 417 is 1
Notice that 1 = HCF(417,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 481, 306, 417?
Answer: HCF of 481, 306, 417 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 481, 306, 417 using Euclid's Algorithm?
Answer: For arbitrary numbers 481, 306, 417 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
