HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 269, 573 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 269, 573 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 493, 269, 573 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 493, 269, 573 is 1.
HCF(493, 269, 573) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 269, 573 is 1.
Step 1: Since 493 > 269, we apply the division lemma to 493 and 269, to get
493 = 269 x 1 + 224
Step 2: Since the reminder 269 ≠ 0, we apply division lemma to 224 and 269, to get
269 = 224 x 1 + 45
Step 3: We consider the new divisor 224 and the new remainder 45, and apply the division lemma to get
224 = 45 x 4 + 44
We consider the new divisor 45 and the new remainder 44,and apply the division lemma to get
45 = 44 x 1 + 1
We consider the new divisor 44 and the new remainder 1,and apply the division lemma to get
44 = 1 x 44 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 493 and 269 is 1
Notice that 1 = HCF(44,1) = HCF(45,44) = HCF(224,45) = HCF(269,224) = HCF(493,269) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 573 > 1, we apply the division lemma to 573 and 1, to get
573 = 1 x 573 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 573 is 1
Notice that 1 = HCF(573,1) .
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 493, 269, 573?
Answer: HCF of 493, 269, 573 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 493, 269, 573 using Euclid's Algorithm?
Answer: For arbitrary numbers 493, 269, 573 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
