HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 647, 873 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 647, 873 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 647, 873 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 647, 873 is 1.
HCF(647, 873) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 647, 873 is 1.
Step 1: Since 873 > 647, we apply the division lemma to 873 and 647, to get
873 = 647 x 1 + 226
Step 2: Since the reminder 647 ≠ 0, we apply division lemma to 226 and 647, to get
647 = 226 x 2 + 195
Step 3: We consider the new divisor 226 and the new remainder 195, and apply the division lemma to get
226 = 195 x 1 + 31
We consider the new divisor 195 and the new remainder 31,and apply the division lemma to get
195 = 31 x 6 + 9
We consider the new divisor 31 and the new remainder 9,and apply the division lemma to get
31 = 9 x 3 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 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 647 and 873 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(31,9) = HCF(195,31) = HCF(226,195) = HCF(647,226) = HCF(873,647) .
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 647, 873?
Answer: HCF of 647, 873 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 647, 873 using Euclid's Algorithm?
Answer: For arbitrary numbers 647, 873 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
