HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 911, 431, 91 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 911, 431, 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 911, 431, 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 911, 431, 91 is 1.
HCF(911, 431, 91) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 911, 431, 91 is 1.
Step 1: Since 911 > 431, we apply the division lemma to 911 and 431, to get
911 = 431 x 2 + 49
Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 49 and 431, to get
431 = 49 x 8 + 39
Step 3: We consider the new divisor 49 and the new remainder 39, and apply the division lemma to get
49 = 39 x 1 + 10
We consider the new divisor 39 and the new remainder 10,and apply the division lemma to get
39 = 10 x 3 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 911 and 431 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(39,10) = HCF(49,39) = HCF(431,49) = HCF(911,431) .
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 911, 431, 91?
Answer: HCF of 911, 431, 91 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 911, 431, 91 using Euclid's Algorithm?
Answer: For arbitrary numbers 911, 431, 91 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
