HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 1899 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 1899 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 487, 1899 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 487, 1899 is 1.
HCF(487, 1899) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 487, 1899 is 1.
Step 1: Since 1899 > 487, we apply the division lemma to 1899 and 487, to get
1899 = 487 x 3 + 438
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 438 and 487, to get
487 = 438 x 1 + 49
Step 3: We consider the new divisor 438 and the new remainder 49, and apply the division lemma to get
438 = 49 x 8 + 46
We consider the new divisor 49 and the new remainder 46,and apply the division lemma to get
49 = 46 x 1 + 3
We consider the new divisor 46 and the new remainder 3,and apply the division lemma to get
46 = 3 x 15 + 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 487 and 1899 is 1
Notice that 1 = HCF(3,1) = HCF(46,3) = HCF(49,46) = HCF(438,49) = HCF(487,438) = HCF(1899,487) .
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 487, 1899?
Answer: HCF of 487, 1899 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 487, 1899 using Euclid's Algorithm?
Answer: For arbitrary numbers 487, 1899 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
