HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 57, 513, 669 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 57, 513, 669 is 3 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 57, 513, 669 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 57, 513, 669 is 3.
HCF(57, 513, 669) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 57, 513, 669 is 3.
Step 1: Since 513 > 57, we apply the division lemma to 513 and 57, to get
513 = 57 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 57, the HCF of 57 and 513 is 57
Notice that 57 = HCF(513,57) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 669 > 57, we apply the division lemma to 669 and 57, to get
669 = 57 x 11 + 42
Step 2: Since the reminder 57 ≠ 0, we apply division lemma to 42 and 57, to get
57 = 42 x 1 + 15
Step 3: We consider the new divisor 42 and the new remainder 15, and apply the division lemma to get
42 = 15 x 2 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 57 and 669 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(42,15) = HCF(57,42) = HCF(669,57) .
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 57, 513, 669?
Answer: HCF of 57, 513, 669 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 57, 513, 669 using Euclid's Algorithm?
Answer: For arbitrary numbers 57, 513, 669 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
