HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 565, 215, 631 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 565, 215, 631 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 565, 215, 631 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 565, 215, 631 is 1.
HCF(565, 215, 631) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 565, 215, 631 is 1.
Step 1: Since 565 > 215, we apply the division lemma to 565 and 215, to get
565 = 215 x 2 + 135
Step 2: Since the reminder 215 ≠ 0, we apply division lemma to 135 and 215, to get
215 = 135 x 1 + 80
Step 3: We consider the new divisor 135 and the new remainder 80, and apply the division lemma to get
135 = 80 x 1 + 55
We consider the new divisor 80 and the new remainder 55,and apply the division lemma to get
80 = 55 x 1 + 25
We consider the new divisor 55 and the new remainder 25,and apply the division lemma to get
55 = 25 x 2 + 5
We consider the new divisor 25 and the new remainder 5,and apply the division lemma to get
25 = 5 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 565 and 215 is 5
Notice that 5 = HCF(25,5) = HCF(55,25) = HCF(80,55) = HCF(135,80) = HCF(215,135) = HCF(565,215) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 631 > 5, we apply the division lemma to 631 and 5, to get
631 = 5 x 126 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, 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 5 and 631 is 1
Notice that 1 = HCF(5,1) = HCF(631,5) .
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 565, 215, 631?
Answer: HCF of 565, 215, 631 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 565, 215, 631 using Euclid's Algorithm?
Answer: For arbitrary numbers 565, 215, 631 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
