HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 676, 69869 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 676, 69869 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 676, 69869 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 676, 69869 is 1.
HCF(676, 69869) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 676, 69869 is 1.
Step 1: Since 69869 > 676, we apply the division lemma to 69869 and 676, to get
69869 = 676 x 103 + 241
Step 2: Since the reminder 676 ≠ 0, we apply division lemma to 241 and 676, to get
676 = 241 x 2 + 194
Step 3: We consider the new divisor 241 and the new remainder 194, and apply the division lemma to get
241 = 194 x 1 + 47
We consider the new divisor 194 and the new remainder 47,and apply the division lemma to get
194 = 47 x 4 + 6
We consider the new divisor 47 and the new remainder 6,and apply the division lemma to get
47 = 6 x 7 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 676 and 69869 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(47,6) = HCF(194,47) = HCF(241,194) = HCF(676,241) = HCF(69869,676) .
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 676, 69869?
Answer: HCF of 676, 69869 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 676, 69869 using Euclid's Algorithm?
Answer: For arbitrary numbers 676, 69869 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
