HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 522, 686, 428 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 522, 686, 428 is 2 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 522, 686, 428 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 522, 686, 428 is 2.
HCF(522, 686, 428) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 522, 686, 428 is 2.
Step 1: Since 686 > 522, we apply the division lemma to 686 and 522, to get
686 = 522 x 1 + 164
Step 2: Since the reminder 522 ≠ 0, we apply division lemma to 164 and 522, to get
522 = 164 x 3 + 30
Step 3: We consider the new divisor 164 and the new remainder 30, and apply the division lemma to get
164 = 30 x 5 + 14
We consider the new divisor 30 and the new remainder 14,and apply the division lemma to get
30 = 14 x 2 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 522 and 686 is 2
Notice that 2 = HCF(14,2) = HCF(30,14) = HCF(164,30) = HCF(522,164) = HCF(686,522) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 428 > 2, we apply the division lemma to 428 and 2, to get
428 = 2 x 214 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 428 is 2
Notice that 2 = HCF(428,2) .
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 522, 686, 428?
Answer: HCF of 522, 686, 428 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 522, 686, 428 using Euclid's Algorithm?
Answer: For arbitrary numbers 522, 686, 428 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
