HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 959, 681, 889 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 959, 681, 889 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 959, 681, 889 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 959, 681, 889 is 1.
HCF(959, 681, 889) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 959, 681, 889 is 1.
Step 1: Since 959 > 681, we apply the division lemma to 959 and 681, to get
959 = 681 x 1 + 278
Step 2: Since the reminder 681 ≠ 0, we apply division lemma to 278 and 681, to get
681 = 278 x 2 + 125
Step 3: We consider the new divisor 278 and the new remainder 125, and apply the division lemma to get
278 = 125 x 2 + 28
We consider the new divisor 125 and the new remainder 28,and apply the division lemma to get
125 = 28 x 4 + 13
We consider the new divisor 28 and the new remainder 13,and apply the division lemma to get
28 = 13 x 2 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 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 959 and 681 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(28,13) = HCF(125,28) = HCF(278,125) = HCF(681,278) = HCF(959,681) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 889 > 1, we apply the division lemma to 889 and 1, to get
889 = 1 x 889 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 889 is 1
Notice that 1 = HCF(889,1) .
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 959, 681, 889?
Answer: HCF of 959, 681, 889 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 959, 681, 889 using Euclid's Algorithm?
Answer: For arbitrary numbers 959, 681, 889 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
