HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 320, 543 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 320, 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 320, 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 320, 543 is 1.
HCF(320, 543) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 320, 543 is 1.
Step 1: Since 543 > 320, we apply the division lemma to 543 and 320, to get
543 = 320 x 1 + 223
Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 223 and 320, to get
320 = 223 x 1 + 97
Step 3: We consider the new divisor 223 and the new remainder 97, and apply the division lemma to get
223 = 97 x 2 + 29
We consider the new divisor 97 and the new remainder 29,and apply the division lemma to get
97 = 29 x 3 + 10
We consider the new divisor 29 and the new remainder 10,and apply the division lemma to get
29 = 10 x 2 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 320 and 543 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(29,10) = HCF(97,29) = HCF(223,97) = HCF(320,223) = HCF(543,320) .
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 320, 543?
Answer: HCF of 320, 543 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 320, 543 using Euclid's Algorithm?
Answer: For arbitrary numbers 320, 543 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
