HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 812, 223 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 581, 812, 223 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 581, 812, 223 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 581, 812, 223 is 1.
HCF(581, 812, 223) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 581, 812, 223 is 1.
Step 1: Since 812 > 581, we apply the division lemma to 812 and 581, to get
812 = 581 x 1 + 231
Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 231 and 581, to get
581 = 231 x 2 + 119
Step 3: We consider the new divisor 231 and the new remainder 119, and apply the division lemma to get
231 = 119 x 1 + 112
We consider the new divisor 119 and the new remainder 112,and apply the division lemma to get
119 = 112 x 1 + 7
We consider the new divisor 112 and the new remainder 7,and apply the division lemma to get
112 = 7 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 581 and 812 is 7
Notice that 7 = HCF(112,7) = HCF(119,112) = HCF(231,119) = HCF(581,231) = HCF(812,581) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 223 > 7, we apply the division lemma to 223 and 7, to get
223 = 7 x 31 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 223 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(223,7) .
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 581, 812, 223?
Answer: HCF of 581, 812, 223 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 581, 812, 223 using Euclid's Algorithm?
Answer: For arbitrary numbers 581, 812, 223 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
