HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 711, 675 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 520, 711, 675 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 520, 711, 675 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 520, 711, 675 is 1.
HCF(520, 711, 675) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 520, 711, 675 is 1.
Step 1: Since 711 > 520, we apply the division lemma to 711 and 520, to get
711 = 520 x 1 + 191
Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 191 and 520, to get
520 = 191 x 2 + 138
Step 3: We consider the new divisor 191 and the new remainder 138, and apply the division lemma to get
191 = 138 x 1 + 53
We consider the new divisor 138 and the new remainder 53,and apply the division lemma to get
138 = 53 x 2 + 32
We consider the new divisor 53 and the new remainder 32,and apply the division lemma to get
53 = 32 x 1 + 21
We consider the new divisor 32 and the new remainder 21,and apply the division lemma to get
32 = 21 x 1 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 520 and 711 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(32,21) = HCF(53,32) = HCF(138,53) = HCF(191,138) = HCF(520,191) = HCF(711,520) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 675 > 1, we apply the division lemma to 675 and 1, to get
675 = 1 x 675 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 675 is 1
Notice that 1 = HCF(675,1) .
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 520, 711, 675?
Answer: HCF of 520, 711, 675 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 520, 711, 675 using Euclid's Algorithm?
Answer: For arbitrary numbers 520, 711, 675 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
