HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 87, 261, 884 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 87, 261, 884 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 87, 261, 884 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 87, 261, 884 is 1.
HCF(87, 261, 884) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 87, 261, 884 is 1.
Step 1: Since 261 > 87, we apply the division lemma to 261 and 87, to get
261 = 87 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 87, the HCF of 87 and 261 is 87
Notice that 87 = HCF(261,87) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 884 > 87, we apply the division lemma to 884 and 87, to get
884 = 87 x 10 + 14
Step 2: Since the reminder 87 ≠ 0, we apply division lemma to 14 and 87, to get
87 = 14 x 6 + 3
Step 3: We consider the new divisor 14 and the new remainder 3, and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 87 and 884 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(87,14) = HCF(884,87) .
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 87, 261, 884?
Answer: HCF of 87, 261, 884 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 87, 261, 884 using Euclid's Algorithm?
Answer: For arbitrary numbers 87, 261, 884 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
