HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 495, 330, 497 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 495, 330, 497 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 495, 330, 497 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 495, 330, 497 is 1.
HCF(495, 330, 497) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 495, 330, 497 is 1.
Step 1: Since 495 > 330, we apply the division lemma to 495 and 330, to get
495 = 330 x 1 + 165
Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 165 and 330, to get
330 = 165 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 165, the HCF of 495 and 330 is 165
Notice that 165 = HCF(330,165) = HCF(495,330) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 497 > 165, we apply the division lemma to 497 and 165, to get
497 = 165 x 3 + 2
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 2 and 165, to get
165 = 2 x 82 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 165 and 497 is 1
Notice that 1 = HCF(2,1) = HCF(165,2) = HCF(497,165) .
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 495, 330, 497?
Answer: HCF of 495, 330, 497 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 495, 330, 497 using Euclid's Algorithm?
Answer: For arbitrary numbers 495, 330, 497 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
