HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 123, 461 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 123, 461 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 123, 461 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 123, 461 is 1.
HCF(123, 461) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 123, 461 is 1.
Step 1: Since 461 > 123, we apply the division lemma to 461 and 123, to get
461 = 123 x 3 + 92
Step 2: Since the reminder 123 ≠ 0, we apply division lemma to 92 and 123, to get
123 = 92 x 1 + 31
Step 3: We consider the new divisor 92 and the new remainder 31, and apply the division lemma to get
92 = 31 x 2 + 30
We consider the new divisor 31 and the new remainder 30,and apply the division lemma to get
31 = 30 x 1 + 1
We consider the new divisor 30 and the new remainder 1,and apply the division lemma to get
30 = 1 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 123 and 461 is 1
Notice that 1 = HCF(30,1) = HCF(31,30) = HCF(92,31) = HCF(123,92) = HCF(461,123) .
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 123, 461?
Answer: HCF of 123, 461 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 123, 461 using Euclid's Algorithm?
Answer: For arbitrary numbers 123, 461 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
