HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 954, 609, 723 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 954, 609, 723 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 954, 609, 723 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 954, 609, 723 is 3.
HCF(954, 609, 723) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 954, 609, 723 is 3.
Step 1: Since 954 > 609, we apply the division lemma to 954 and 609, to get
954 = 609 x 1 + 345
Step 2: Since the reminder 609 ≠ 0, we apply division lemma to 345 and 609, to get
609 = 345 x 1 + 264
Step 3: We consider the new divisor 345 and the new remainder 264, and apply the division lemma to get
345 = 264 x 1 + 81
We consider the new divisor 264 and the new remainder 81,and apply the division lemma to get
264 = 81 x 3 + 21
We consider the new divisor 81 and the new remainder 21,and apply the division lemma to get
81 = 21 x 3 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 954 and 609 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(81,21) = HCF(264,81) = HCF(345,264) = HCF(609,345) = HCF(954,609) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 723 > 3, we apply the division lemma to 723 and 3, to get
723 = 3 x 241 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 723 is 3
Notice that 3 = HCF(723,3) .
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 954, 609, 723?
Answer: HCF of 954, 609, 723 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 954, 609, 723 using Euclid's Algorithm?
Answer: For arbitrary numbers 954, 609, 723 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
