HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 320, 580, 820 i.e. 20 the largest integer that leaves a remainder zero for all numbers.
HCF of 320, 580, 820 is 20 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 320, 580, 820 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 320, 580, 820 is 20.
HCF(320, 580, 820) = 20
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 320, 580, 820 is 20.
Step 1: Since 580 > 320, we apply the division lemma to 580 and 320, to get
580 = 320 x 1 + 260
Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 260 and 320, to get
320 = 260 x 1 + 60
Step 3: We consider the new divisor 260 and the new remainder 60, and apply the division lemma to get
260 = 60 x 4 + 20
We consider the new divisor 60 and the new remainder 20, and apply the division lemma to get
60 = 20 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 320 and 580 is 20
Notice that 20 = HCF(60,20) = HCF(260,60) = HCF(320,260) = HCF(580,320) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 820 > 20, we apply the division lemma to 820 and 20, to get
820 = 20 x 41 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 20 and 820 is 20
Notice that 20 = HCF(820,20) .
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 320, 580, 820?
Answer: HCF of 320, 580, 820 is 20 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 320, 580, 820 using Euclid's Algorithm?
Answer: For arbitrary numbers 320, 580, 820 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
