HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 367, 81 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 367, 81 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 367, 81 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 367, 81 is 1.
HCF(367, 81) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 367, 81 is 1.
Step 1: Since 367 > 81, we apply the division lemma to 367 and 81, to get
367 = 81 x 4 + 43
Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 43 and 81, to get
81 = 43 x 1 + 38
Step 3: We consider the new divisor 43 and the new remainder 38, and apply the division lemma to get
43 = 38 x 1 + 5
We consider the new divisor 38 and the new remainder 5,and apply the division lemma to get
38 = 5 x 7 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
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 367 and 81 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(38,5) = HCF(43,38) = HCF(81,43) = HCF(367,81) .
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 367, 81?
Answer: HCF of 367, 81 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 367, 81 using Euclid's Algorithm?
Answer: For arbitrary numbers 367, 81 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
