HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 477, 580, 520 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 477, 580, 520 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 477, 580, 520 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 477, 580, 520 is 1.
HCF(477, 580, 520) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 477, 580, 520 is 1.
Step 1: Since 580 > 477, we apply the division lemma to 580 and 477, to get
580 = 477 x 1 + 103
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 103 and 477, to get
477 = 103 x 4 + 65
Step 3: We consider the new divisor 103 and the new remainder 65, and apply the division lemma to get
103 = 65 x 1 + 38
We consider the new divisor 65 and the new remainder 38,and apply the division lemma to get
65 = 38 x 1 + 27
We consider the new divisor 38 and the new remainder 27,and apply the division lemma to get
38 = 27 x 1 + 11
We consider the new divisor 27 and the new remainder 11,and apply the division lemma to get
27 = 11 x 2 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 477 and 580 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(27,11) = HCF(38,27) = HCF(65,38) = HCF(103,65) = HCF(477,103) = HCF(580,477) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 520 > 1, we apply the division lemma to 520 and 1, to get
520 = 1 x 520 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 520 is 1
Notice that 1 = HCF(520,1) .
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 477, 580, 520?
Answer: HCF of 477, 580, 520 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 477, 580, 520 using Euclid's Algorithm?
Answer: For arbitrary numbers 477, 580, 520 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
