HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 631, 403, 623 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 631, 403, 623 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 631, 403, 623 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 631, 403, 623 is 1.
HCF(631, 403, 623) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 631, 403, 623 is 1.
Step 1: Since 631 > 403, we apply the division lemma to 631 and 403, to get
631 = 403 x 1 + 228
Step 2: Since the reminder 403 ≠ 0, we apply division lemma to 228 and 403, to get
403 = 228 x 1 + 175
Step 3: We consider the new divisor 228 and the new remainder 175, and apply the division lemma to get
228 = 175 x 1 + 53
We consider the new divisor 175 and the new remainder 53,and apply the division lemma to get
175 = 53 x 3 + 16
We consider the new divisor 53 and the new remainder 16,and apply the division lemma to get
53 = 16 x 3 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 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 631 and 403 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(53,16) = HCF(175,53) = HCF(228,175) = HCF(403,228) = HCF(631,403) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 623 > 1, we apply the division lemma to 623 and 1, to get
623 = 1 x 623 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 623 is 1
Notice that 1 = HCF(623,1) .
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 631, 403, 623?
Answer: HCF of 631, 403, 623 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 631, 403, 623 using Euclid's Algorithm?
Answer: For arbitrary numbers 631, 403, 623 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
