HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 419, 518 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 419, 518 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 816, 419, 518 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 816, 419, 518 is 1.
HCF(816, 419, 518) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 816, 419, 518 is 1.
Step 1: Since 816 > 419, we apply the division lemma to 816 and 419, to get
816 = 419 x 1 + 397
Step 2: Since the reminder 419 ≠ 0, we apply division lemma to 397 and 419, to get
419 = 397 x 1 + 22
Step 3: We consider the new divisor 397 and the new remainder 22, and apply the division lemma to get
397 = 22 x 18 + 1
We consider the new divisor 22 and the new remainder 1, and apply the division lemma to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 816 and 419 is 1
Notice that 1 = HCF(22,1) = HCF(397,22) = HCF(419,397) = HCF(816,419) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 518 > 1, we apply the division lemma to 518 and 1, to get
518 = 1 x 518 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 518 is 1
Notice that 1 = HCF(518,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 816, 419, 518?
Answer: HCF of 816, 419, 518 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 816, 419, 518 using Euclid's Algorithm?
Answer: For arbitrary numbers 816, 419, 518 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
