HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 202, 317 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 202, 317 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 202, 317 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 202, 317 is 1.
HCF(202, 317) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 202, 317 is 1.
Step 1: Since 317 > 202, we apply the division lemma to 317 and 202, to get
317 = 202 x 1 + 115
Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 115 and 202, to get
202 = 115 x 1 + 87
Step 3: We consider the new divisor 115 and the new remainder 87, and apply the division lemma to get
115 = 87 x 1 + 28
We consider the new divisor 87 and the new remainder 28,and apply the division lemma to get
87 = 28 x 3 + 3
We consider the new divisor 28 and the new remainder 3,and apply the division lemma to get
28 = 3 x 9 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 202 and 317 is 1
Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(87,28) = HCF(115,87) = HCF(202,115) = HCF(317,202) .
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 202, 317?
Answer: HCF of 202, 317 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 202, 317 using Euclid's Algorithm?
Answer: For arbitrary numbers 202, 317 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
