HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 1517 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 1517 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 493, 1517 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 493, 1517 is 1.
HCF(493, 1517) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 1517 is 1.
Step 1: Since 1517 > 493, we apply the division lemma to 1517 and 493, to get
1517 = 493 x 3 + 38
Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 38 and 493, to get
493 = 38 x 12 + 37
Step 3: We consider the new divisor 38 and the new remainder 37, and apply the division lemma to get
38 = 37 x 1 + 1
We consider the new divisor 37 and the new remainder 1, and apply the division lemma to get
37 = 1 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 493 and 1517 is 1
Notice that 1 = HCF(37,1) = HCF(38,37) = HCF(493,38) = HCF(1517,493) .
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 493, 1517?
Answer: HCF of 493, 1517 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 493, 1517 using Euclid's Algorithm?
Answer: For arbitrary numbers 493, 1517 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
