HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 487 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 705, 487 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 705, 487 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 705, 487 is 1.
HCF(705, 487) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 705, 487 is 1.
Step 1: Since 705 > 487, we apply the division lemma to 705 and 487, to get
705 = 487 x 1 + 218
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 218 and 487, to get
487 = 218 x 2 + 51
Step 3: We consider the new divisor 218 and the new remainder 51, and apply the division lemma to get
218 = 51 x 4 + 14
We consider the new divisor 51 and the new remainder 14,and apply the division lemma to get
51 = 14 x 3 + 9
We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get
14 = 9 x 1 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 705 and 487 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(51,14) = HCF(218,51) = HCF(487,218) = HCF(705,487) .
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 705, 487?
Answer: HCF of 705, 487 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 705, 487 using Euclid's Algorithm?
Answer: For arbitrary numbers 705, 487 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
