HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 27, 41, 66, 801 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 27, 41, 66, 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 27, 41, 66, 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 27, 41, 66, 801 is 1.
HCF(27, 41, 66, 801) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 27, 41, 66, 801 is 1.
Step 1: Since 41 > 27, we apply the division lemma to 41 and 27, to get
41 = 27 x 1 + 14
Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 14 and 27, to get
27 = 14 x 1 + 13
Step 3: We consider the new divisor 14 and the new remainder 13, and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1, and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 27 and 41 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(27,14) = HCF(41,27) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66 > 1, we apply the division lemma to 66 and 1, to get
66 = 1 x 66 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 66 is 1
Notice that 1 = HCF(66,1) .
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 27, 41, 66, 801?
Answer: HCF of 27, 41, 66, 801 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 27, 41, 66, 801 using Euclid's Algorithm?
Answer: For arbitrary numbers 27, 41, 66, 801 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
