HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 762 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 515, 762 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 515, 762 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 515, 762 is 1.
HCF(515, 762) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 515, 762 is 1.
Step 1: Since 762 > 515, we apply the division lemma to 762 and 515, to get
762 = 515 x 1 + 247
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 247 and 515, to get
515 = 247 x 2 + 21
Step 3: We consider the new divisor 247 and the new remainder 21, and apply the division lemma to get
247 = 21 x 11 + 16
We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get
21 = 16 x 1 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 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 515 and 762 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(247,21) = HCF(515,247) = HCF(762,515) .
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 515, 762?
Answer: HCF of 515, 762 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 515, 762 using Euclid's Algorithm?
Answer: For arbitrary numbers 515, 762 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
