HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 197, 482, 515 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 197, 482, 515 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 197, 482, 515 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 197, 482, 515 is 1.
HCF(197, 482, 515) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 197, 482, 515 is 1.
Step 1: Since 482 > 197, we apply the division lemma to 482 and 197, to get
482 = 197 x 2 + 88
Step 2: Since the reminder 197 ≠ 0, we apply division lemma to 88 and 197, to get
197 = 88 x 2 + 21
Step 3: We consider the new divisor 88 and the new remainder 21, and apply the division lemma to get
88 = 21 x 4 + 4
We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get
21 = 4 x 5 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 197 and 482 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(88,21) = HCF(197,88) = HCF(482,197) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 515 > 1, we apply the division lemma to 515 and 1, to get
515 = 1 x 515 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 515 is 1
Notice that 1 = HCF(515,1) .
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 197, 482, 515?
Answer: HCF of 197, 482, 515 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 197, 482, 515 using Euclid's Algorithm?
Answer: For arbitrary numbers 197, 482, 515 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
