HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 69, 46, 130 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 69, 46, 130 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 69, 46, 130 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 69, 46, 130 is 1.
HCF(69, 46, 130) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 69, 46, 130 is 1.
Step 1: Since 69 > 46, we apply the division lemma to 69 and 46, to get
69 = 46 x 1 + 23
Step 2: Since the reminder 46 ≠ 0, we apply division lemma to 23 and 46, to get
46 = 23 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 69 and 46 is 23
Notice that 23 = HCF(46,23) = HCF(69,46) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 130 > 23, we apply the division lemma to 130 and 23, to get
130 = 23 x 5 + 15
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 15 and 23, to get
23 = 15 x 1 + 8
Step 3: We consider the new divisor 15 and the new remainder 8, and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 23 and 130 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(130,23) .
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 69, 46, 130?
Answer: HCF of 69, 46, 130 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 69, 46, 130 using Euclid's Algorithm?
Answer: For arbitrary numbers 69, 46, 130 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
