HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 405 i.e. 81 the largest integer that leaves a remainder zero for all numbers.
HCF of 486, 405 is 81 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 486, 405 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 486, 405 is 81.
HCF(486, 405) = 81
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 486, 405 is 81.
Step 1: Since 486 > 405, we apply the division lemma to 486 and 405, to get
486 = 405 x 1 + 81
Step 2: Since the reminder 405 ≠ 0, we apply division lemma to 81 and 405, to get
405 = 81 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 81, the HCF of 486 and 405 is 81
Notice that 81 = HCF(405,81) = HCF(486,405) .
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 486, 405?
Answer: HCF of 486, 405 is 81 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 486, 405 using Euclid's Algorithm?
Answer: For arbitrary numbers 486, 405 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
