HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 347, 296 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 491, 347, 296 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 491, 347, 296 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 491, 347, 296 is 1.
HCF(491, 347, 296) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 491, 347, 296 is 1.
Step 1: Since 491 > 347, we apply the division lemma to 491 and 347, to get
491 = 347 x 1 + 144
Step 2: Since the reminder 347 ≠ 0, we apply division lemma to 144 and 347, to get
347 = 144 x 2 + 59
Step 3: We consider the new divisor 144 and the new remainder 59, and apply the division lemma to get
144 = 59 x 2 + 26
We consider the new divisor 59 and the new remainder 26,and apply the division lemma to get
59 = 26 x 2 + 7
We consider the new divisor 26 and the new remainder 7,and apply the division lemma to get
26 = 7 x 3 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 491 and 347 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(26,7) = HCF(59,26) = HCF(144,59) = HCF(347,144) = HCF(491,347) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 296 > 1, we apply the division lemma to 296 and 1, to get
296 = 1 x 296 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 296 is 1
Notice that 1 = HCF(296,1) .
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 491, 347, 296?
Answer: HCF of 491, 347, 296 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 491, 347, 296 using Euclid's Algorithm?
Answer: For arbitrary numbers 491, 347, 296 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
