HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 409, 541, 801 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 409, 541, 801 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 409, 541, 801 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 409, 541, 801 is 1.
HCF(409, 541, 801) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 409, 541, 801 is 1.
Step 1: Since 541 > 409, we apply the division lemma to 541 and 409, to get
541 = 409 x 1 + 132
Step 2: Since the reminder 409 ≠ 0, we apply division lemma to 132 and 409, to get
409 = 132 x 3 + 13
Step 3: We consider the new divisor 132 and the new remainder 13, and apply the division lemma to get
132 = 13 x 10 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 409 and 541 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(132,13) = HCF(409,132) = HCF(541,409) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 801 > 1, we apply the division lemma to 801 and 1, to get
801 = 1 x 801 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 801 is 1
Notice that 1 = HCF(801,1) .
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 409, 541, 801?
Answer: HCF of 409, 541, 801 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 409, 541, 801 using Euclid's Algorithm?
Answer: For arbitrary numbers 409, 541, 801 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
