HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 712, 181 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 801, 712, 181 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 801, 712, 181 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 801, 712, 181 is 1.
HCF(801, 712, 181) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 801, 712, 181 is 1.
Step 1: Since 801 > 712, we apply the division lemma to 801 and 712, to get
801 = 712 x 1 + 89
Step 2: Since the reminder 712 ≠ 0, we apply division lemma to 89 and 712, to get
712 = 89 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 89, the HCF of 801 and 712 is 89
Notice that 89 = HCF(712,89) = HCF(801,712) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 181 > 89, we apply the division lemma to 181 and 89, to get
181 = 89 x 2 + 3
Step 2: Since the reminder 89 ≠ 0, we apply division lemma to 3 and 89, to get
89 = 3 x 29 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 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 89 and 181 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(89,3) = HCF(181,89) .
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 801, 712, 181?
Answer: HCF of 801, 712, 181 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 801, 712, 181 using Euclid's Algorithm?
Answer: For arbitrary numbers 801, 712, 181 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
