HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 879, 963, 449 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 879, 963, 449 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 879, 963, 449 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 879, 963, 449 is 1.
HCF(879, 963, 449) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 879, 963, 449 is 1.
Step 1: Since 963 > 879, we apply the division lemma to 963 and 879, to get
963 = 879 x 1 + 84
Step 2: Since the reminder 879 ≠ 0, we apply division lemma to 84 and 879, to get
879 = 84 x 10 + 39
Step 3: We consider the new divisor 84 and the new remainder 39, and apply the division lemma to get
84 = 39 x 2 + 6
We consider the new divisor 39 and the new remainder 6,and apply the division lemma to get
39 = 6 x 6 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 879 and 963 is 3
Notice that 3 = HCF(6,3) = HCF(39,6) = HCF(84,39) = HCF(879,84) = HCF(963,879) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 449 > 3, we apply the division lemma to 449 and 3, to get
449 = 3 x 149 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 449 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(449,3) .
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 879, 963, 449?
Answer: HCF of 879, 963, 449 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 879, 963, 449 using Euclid's Algorithm?
Answer: For arbitrary numbers 879, 963, 449 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
