HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 518, 905, 284 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 518, 905, 284 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 518, 905, 284 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 518, 905, 284 is 1.
HCF(518, 905, 284) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 518, 905, 284 is 1.
Step 1: Since 905 > 518, we apply the division lemma to 905 and 518, to get
905 = 518 x 1 + 387
Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 387 and 518, to get
518 = 387 x 1 + 131
Step 3: We consider the new divisor 387 and the new remainder 131, and apply the division lemma to get
387 = 131 x 2 + 125
We consider the new divisor 131 and the new remainder 125,and apply the division lemma to get
131 = 125 x 1 + 6
We consider the new divisor 125 and the new remainder 6,and apply the division lemma to get
125 = 6 x 20 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 518 and 905 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(125,6) = HCF(131,125) = HCF(387,131) = HCF(518,387) = HCF(905,518) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 284 > 1, we apply the division lemma to 284 and 1, to get
284 = 1 x 284 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 284 is 1
Notice that 1 = HCF(284,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 518, 905, 284?
Answer: HCF of 518, 905, 284 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 518, 905, 284 using Euclid's Algorithm?
Answer: For arbitrary numbers 518, 905, 284 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
