HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 772, 543 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 772, 543 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 772, 543 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 772, 543 is 1.
HCF(772, 543) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 772, 543 is 1.
Step 1: Since 772 > 543, we apply the division lemma to 772 and 543, to get
772 = 543 x 1 + 229
Step 2: Since the reminder 543 ≠ 0, we apply division lemma to 229 and 543, to get
543 = 229 x 2 + 85
Step 3: We consider the new divisor 229 and the new remainder 85, and apply the division lemma to get
229 = 85 x 2 + 59
We consider the new divisor 85 and the new remainder 59,and apply the division lemma to get
85 = 59 x 1 + 26
We consider the new divisor 59 and the new remainder 26,and apply the division lemma to get
59 = 26 x 2 + 7
We consider the new divisor 26 and the new remainder 7,and apply the division lemma to get
26 = 7 x 3 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 772 and 543 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(26,7) = HCF(59,26) = HCF(85,59) = HCF(229,85) = HCF(543,229) = HCF(772,543) .
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 772, 543?
Answer: HCF of 772, 543 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 772, 543 using Euclid's Algorithm?
Answer: For arbitrary numbers 772, 543 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
