HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 815, 479, 360 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 815, 479, 360 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 815, 479, 360 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 815, 479, 360 is 1.
HCF(815, 479, 360) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 815, 479, 360 is 1.
Step 1: Since 815 > 479, we apply the division lemma to 815 and 479, to get
815 = 479 x 1 + 336
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 336 and 479, to get
479 = 336 x 1 + 143
Step 3: We consider the new divisor 336 and the new remainder 143, and apply the division lemma to get
336 = 143 x 2 + 50
We consider the new divisor 143 and the new remainder 50,and apply the division lemma to get
143 = 50 x 2 + 43
We consider the new divisor 50 and the new remainder 43,and apply the division lemma to get
50 = 43 x 1 + 7
We consider the new divisor 43 and the new remainder 7,and apply the division lemma to get
43 = 7 x 6 + 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 815 and 479 is 1
Notice that 1 = HCF(7,1) = HCF(43,7) = HCF(50,43) = HCF(143,50) = HCF(336,143) = HCF(479,336) = HCF(815,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 360 > 1, we apply the division lemma to 360 and 1, to get
360 = 1 x 360 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 360 is 1
Notice that 1 = HCF(360,1) .
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 815, 479, 360?
Answer: HCF of 815, 479, 360 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 815, 479, 360 using Euclid's Algorithm?
Answer: For arbitrary numbers 815, 479, 360 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
