HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 817, 516, 795 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 817, 516, 795 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 817, 516, 795 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 817, 516, 795 is 1.
HCF(817, 516, 795) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 817, 516, 795 is 1.
Step 1: Since 817 > 516, we apply the division lemma to 817 and 516, to get
817 = 516 x 1 + 301
Step 2: Since the reminder 516 ≠ 0, we apply division lemma to 301 and 516, to get
516 = 301 x 1 + 215
Step 3: We consider the new divisor 301 and the new remainder 215, and apply the division lemma to get
301 = 215 x 1 + 86
We consider the new divisor 215 and the new remainder 86,and apply the division lemma to get
215 = 86 x 2 + 43
We consider the new divisor 86 and the new remainder 43,and apply the division lemma to get
86 = 43 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 43, the HCF of 817 and 516 is 43
Notice that 43 = HCF(86,43) = HCF(215,86) = HCF(301,215) = HCF(516,301) = HCF(817,516) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 795 > 43, we apply the division lemma to 795 and 43, to get
795 = 43 x 18 + 21
Step 2: Since the reminder 43 ≠ 0, we apply division lemma to 21 and 43, to get
43 = 21 x 2 + 1
Step 3: We consider the new divisor 21 and the new remainder 1, and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 43 and 795 is 1
Notice that 1 = HCF(21,1) = HCF(43,21) = HCF(795,43) .
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 817, 516, 795?
Answer: HCF of 817, 516, 795 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 817, 516, 795 using Euclid's Algorithm?
Answer: For arbitrary numbers 817, 516, 795 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
