HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 706, 809, 712 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 706, 809, 712 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 706, 809, 712 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 706, 809, 712 is 1.
HCF(706, 809, 712) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 706, 809, 712 is 1.
Step 1: Since 809 > 706, we apply the division lemma to 809 and 706, to get
809 = 706 x 1 + 103
Step 2: Since the reminder 706 ≠ 0, we apply division lemma to 103 and 706, to get
706 = 103 x 6 + 88
Step 3: We consider the new divisor 103 and the new remainder 88, and apply the division lemma to get
103 = 88 x 1 + 15
We consider the new divisor 88 and the new remainder 15,and apply the division lemma to get
88 = 15 x 5 + 13
We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get
15 = 13 x 1 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 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 706 and 809 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(88,15) = HCF(103,88) = HCF(706,103) = HCF(809,706) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 712 > 1, we apply the division lemma to 712 and 1, to get
712 = 1 x 712 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 712 is 1
Notice that 1 = HCF(712,1) .
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 706, 809, 712?
Answer: HCF of 706, 809, 712 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 706, 809, 712 using Euclid's Algorithm?
Answer: For arbitrary numbers 706, 809, 712 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
