HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 458, 570 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 458, 570 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 458, 570 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 458, 570 is 2.
HCF(458, 570) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 458, 570 is 2.
Step 1: Since 570 > 458, we apply the division lemma to 570 and 458, to get
570 = 458 x 1 + 112
Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 112 and 458, to get
458 = 112 x 4 + 10
Step 3: We consider the new divisor 112 and the new remainder 10, and apply the division lemma to get
112 = 10 x 11 + 2
We consider the new divisor 10 and the new remainder 2, and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 458 and 570 is 2
Notice that 2 = HCF(10,2) = HCF(112,10) = HCF(458,112) = HCF(570,458) .
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 458, 570?
Answer: HCF of 458, 570 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 458, 570 using Euclid's Algorithm?
Answer: For arbitrary numbers 458, 570 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
