HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8120, 515 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 8120, 515 is 5 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 8120, 515 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 8120, 515 is 5.
HCF(8120, 515) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8120, 515 is 5.
Step 1: Since 8120 > 515, we apply the division lemma to 8120 and 515, to get
8120 = 515 x 15 + 395
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 395 and 515, to get
515 = 395 x 1 + 120
Step 3: We consider the new divisor 395 and the new remainder 120, and apply the division lemma to get
395 = 120 x 3 + 35
We consider the new divisor 120 and the new remainder 35,and apply the division lemma to get
120 = 35 x 3 + 15
We consider the new divisor 35 and the new remainder 15,and apply the division lemma to get
35 = 15 x 2 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 8120 and 515 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(120,35) = HCF(395,120) = HCF(515,395) = HCF(8120,515) .
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 8120, 515?
Answer: HCF of 8120, 515 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 8120, 515 using Euclid's Algorithm?
Answer: For arbitrary numbers 8120, 515 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
