HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 878, 821, 864 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 878, 821, 864 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 878, 821, 864 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 878, 821, 864 is 1.
HCF(878, 821, 864) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 878, 821, 864 is 1.
Step 1: Since 878 > 821, we apply the division lemma to 878 and 821, to get
878 = 821 x 1 + 57
Step 2: Since the reminder 821 ≠ 0, we apply division lemma to 57 and 821, to get
821 = 57 x 14 + 23
Step 3: We consider the new divisor 57 and the new remainder 23, and apply the division lemma to get
57 = 23 x 2 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 878 and 821 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(57,23) = HCF(821,57) = HCF(878,821) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 864 > 1, we apply the division lemma to 864 and 1, to get
864 = 1 x 864 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 864 is 1
Notice that 1 = HCF(864,1) .
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 878, 821, 864?
Answer: HCF of 878, 821, 864 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 878, 821, 864 using Euclid's Algorithm?
Answer: For arbitrary numbers 878, 821, 864 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
