HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 747, 905, 513 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 747, 905, 513 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 747, 905, 513 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 747, 905, 513 is 1.
HCF(747, 905, 513) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 747, 905, 513 is 1.
Step 1: Since 905 > 747, we apply the division lemma to 905 and 747, to get
905 = 747 x 1 + 158
Step 2: Since the reminder 747 ≠ 0, we apply division lemma to 158 and 747, to get
747 = 158 x 4 + 115
Step 3: We consider the new divisor 158 and the new remainder 115, and apply the division lemma to get
158 = 115 x 1 + 43
We consider the new divisor 115 and the new remainder 43,and apply the division lemma to get
115 = 43 x 2 + 29
We consider the new divisor 43 and the new remainder 29,and apply the division lemma to get
43 = 29 x 1 + 14
We consider the new divisor 29 and the new remainder 14,and apply the division lemma to get
29 = 14 x 2 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 747 and 905 is 1
Notice that 1 = HCF(14,1) = HCF(29,14) = HCF(43,29) = HCF(115,43) = HCF(158,115) = HCF(747,158) = HCF(905,747) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 513 > 1, we apply the division lemma to 513 and 1, to get
513 = 1 x 513 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 513 is 1
Notice that 1 = HCF(513,1) .
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 747, 905, 513?
Answer: HCF of 747, 905, 513 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 747, 905, 513 using Euclid's Algorithm?
Answer: For arbitrary numbers 747, 905, 513 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
