HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 517, 823 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 517, 823 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 517, 823 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 517, 823 is 1.
HCF(517, 823) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 517, 823 is 1.
Step 1: Since 823 > 517, we apply the division lemma to 823 and 517, to get
823 = 517 x 1 + 306
Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 306 and 517, to get
517 = 306 x 1 + 211
Step 3: We consider the new divisor 306 and the new remainder 211, and apply the division lemma to get
306 = 211 x 1 + 95
We consider the new divisor 211 and the new remainder 95,and apply the division lemma to get
211 = 95 x 2 + 21
We consider the new divisor 95 and the new remainder 21,and apply the division lemma to get
95 = 21 x 4 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 517 and 823 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(95,21) = HCF(211,95) = HCF(306,211) = HCF(517,306) = HCF(823,517) .
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 517, 823?
Answer: HCF of 517, 823 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 517, 823 using Euclid's Algorithm?
Answer: For arbitrary numbers 517, 823 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
