HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 538, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 538, 681 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 538, 681 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 538, 681 is 1.
HCF(538, 681) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 538, 681 is 1.
Step 1: Since 681 > 538, we apply the division lemma to 681 and 538, to get
681 = 538 x 1 + 143
Step 2: Since the reminder 538 ≠ 0, we apply division lemma to 143 and 538, to get
538 = 143 x 3 + 109
Step 3: We consider the new divisor 143 and the new remainder 109, and apply the division lemma to get
143 = 109 x 1 + 34
We consider the new divisor 109 and the new remainder 34,and apply the division lemma to get
109 = 34 x 3 + 7
We consider the new divisor 34 and the new remainder 7,and apply the division lemma to get
34 = 7 x 4 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 538 and 681 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(34,7) = HCF(109,34) = HCF(143,109) = HCF(538,143) = HCF(681,538) .
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 538, 681?
Answer: HCF of 538, 681 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 538, 681 using Euclid's Algorithm?
Answer: For arbitrary numbers 538, 681 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
