HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 311, 537, 91 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 311, 537, 91 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 311, 537, 91 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 311, 537, 91 is 1.
HCF(311, 537, 91) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 311, 537, 91 is 1.
Step 1: Since 537 > 311, we apply the division lemma to 537 and 311, to get
537 = 311 x 1 + 226
Step 2: Since the reminder 311 ≠ 0, we apply division lemma to 226 and 311, to get
311 = 226 x 1 + 85
Step 3: We consider the new divisor 226 and the new remainder 85, and apply the division lemma to get
226 = 85 x 2 + 56
We consider the new divisor 85 and the new remainder 56,and apply the division lemma to get
85 = 56 x 1 + 29
We consider the new divisor 56 and the new remainder 29,and apply the division lemma to get
56 = 29 x 1 + 27
We consider the new divisor 29 and the new remainder 27,and apply the division lemma to get
29 = 27 x 1 + 2
We consider the new divisor 27 and the new remainder 2,and apply the division lemma to get
27 = 2 x 13 + 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 311 and 537 is 1
Notice that 1 = HCF(2,1) = HCF(27,2) = HCF(29,27) = HCF(56,29) = HCF(85,56) = HCF(226,85) = HCF(311,226) = HCF(537,311) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91 > 1, we apply the division lemma to 91 and 1, to get
91 = 1 x 91 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 91 is 1
Notice that 1 = HCF(91,1) .
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 311, 537, 91?
Answer: HCF of 311, 537, 91 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 311, 537, 91 using Euclid's Algorithm?
Answer: For arbitrary numbers 311, 537, 91 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
