HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 415, 565, 59 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 415, 565, 59 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 415, 565, 59 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 415, 565, 59 is 1.
HCF(415, 565, 59) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 415, 565, 59 is 1.
Step 1: Since 565 > 415, we apply the division lemma to 565 and 415, to get
565 = 415 x 1 + 150
Step 2: Since the reminder 415 ≠ 0, we apply division lemma to 150 and 415, to get
415 = 150 x 2 + 115
Step 3: We consider the new divisor 150 and the new remainder 115, and apply the division lemma to get
150 = 115 x 1 + 35
We consider the new divisor 115 and the new remainder 35,and apply the division lemma to get
115 = 35 x 3 + 10
We consider the new divisor 35 and the new remainder 10,and apply the division lemma to get
35 = 10 x 3 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 415 and 565 is 5
Notice that 5 = HCF(10,5) = HCF(35,10) = HCF(115,35) = HCF(150,115) = HCF(415,150) = HCF(565,415) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 59 > 5, we apply the division lemma to 59 and 5, to get
59 = 5 x 11 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 59 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(59,5) .
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 415, 565, 59?
Answer: HCF of 415, 565, 59 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 415, 565, 59 using Euclid's Algorithm?
Answer: For arbitrary numbers 415, 565, 59 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
