HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 871, 980, 159 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 871, 980, 159 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 871, 980, 159 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 871, 980, 159 is 1.
HCF(871, 980, 159) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 871, 980, 159 is 1.
Step 1: Since 980 > 871, we apply the division lemma to 980 and 871, to get
980 = 871 x 1 + 109
Step 2: Since the reminder 871 ≠ 0, we apply division lemma to 109 and 871, to get
871 = 109 x 7 + 108
Step 3: We consider the new divisor 109 and the new remainder 108, and apply the division lemma to get
109 = 108 x 1 + 1
We consider the new divisor 108 and the new remainder 1, and apply the division lemma to get
108 = 1 x 108 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 871 and 980 is 1
Notice that 1 = HCF(108,1) = HCF(109,108) = HCF(871,109) = HCF(980,871) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 159 > 1, we apply the division lemma to 159 and 1, to get
159 = 1 x 159 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 159 is 1
Notice that 1 = HCF(159,1) .
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 871, 980, 159?
Answer: HCF of 871, 980, 159 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 871, 980, 159 using Euclid's Algorithm?
Answer: For arbitrary numbers 871, 980, 159 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
