HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 771 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 571, 771 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 571, 771 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 571, 771 is 1.
HCF(571, 771) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 571, 771 is 1.
Step 1: Since 771 > 571, we apply the division lemma to 771 and 571, to get
771 = 571 x 1 + 200
Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 200 and 571, to get
571 = 200 x 2 + 171
Step 3: We consider the new divisor 200 and the new remainder 171, and apply the division lemma to get
200 = 171 x 1 + 29
We consider the new divisor 171 and the new remainder 29,and apply the division lemma to get
171 = 29 x 5 + 26
We consider the new divisor 29 and the new remainder 26,and apply the division lemma to get
29 = 26 x 1 + 3
We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get
26 = 3 x 8 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 571 and 771 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(29,26) = HCF(171,29) = HCF(200,171) = HCF(571,200) = HCF(771,571) .
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 571, 771?
Answer: HCF of 571, 771 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 571, 771 using Euclid's Algorithm?
Answer: For arbitrary numbers 571, 771 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
