HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 251, 868 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 251, 868 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 251, 868 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 251, 868 is 1.
HCF(251, 868) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 251, 868 is 1.
Step 1: Since 868 > 251, we apply the division lemma to 868 and 251, to get
868 = 251 x 3 + 115
Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 115 and 251, to get
251 = 115 x 2 + 21
Step 3: We consider the new divisor 115 and the new remainder 21, and apply the division lemma to get
115 = 21 x 5 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 251 and 868 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(115,21) = HCF(251,115) = HCF(868,251) .
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 251, 868?
Answer: HCF of 251, 868 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 251, 868 using Euclid's Algorithm?
Answer: For arbitrary numbers 251, 868 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
