HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 231 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 622, 231 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 622, 231 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 622, 231 is 1.
HCF(622, 231) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 622, 231 is 1.
Step 1: Since 622 > 231, we apply the division lemma to 622 and 231, to get
622 = 231 x 2 + 160
Step 2: Since the reminder 231 ≠ 0, we apply division lemma to 160 and 231, to get
231 = 160 x 1 + 71
Step 3: We consider the new divisor 160 and the new remainder 71, and apply the division lemma to get
160 = 71 x 2 + 18
We consider the new divisor 71 and the new remainder 18,and apply the division lemma to get
71 = 18 x 3 + 17
We consider the new divisor 18 and the new remainder 17,and apply the division lemma to get
18 = 17 x 1 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 622 and 231 is 1
Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(71,18) = HCF(160,71) = HCF(231,160) = HCF(622,231) .
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 622, 231?
Answer: HCF of 622, 231 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 622, 231 using Euclid's Algorithm?
Answer: For arbitrary numbers 622, 231 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
