HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 609, 723, 406 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 609, 723, 406 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 609, 723, 406 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 609, 723, 406 is 1.
HCF(609, 723, 406) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 609, 723, 406 is 1.
Step 1: Since 723 > 609, we apply the division lemma to 723 and 609, to get
723 = 609 x 1 + 114
Step 2: Since the reminder 609 ≠ 0, we apply division lemma to 114 and 609, to get
609 = 114 x 5 + 39
Step 3: We consider the new divisor 114 and the new remainder 39, and apply the division lemma to get
114 = 39 x 2 + 36
We consider the new divisor 39 and the new remainder 36,and apply the division lemma to get
39 = 36 x 1 + 3
We consider the new divisor 36 and the new remainder 3,and apply the division lemma to get
36 = 3 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 609 and 723 is 3
Notice that 3 = HCF(36,3) = HCF(39,36) = HCF(114,39) = HCF(609,114) = HCF(723,609) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 406 > 3, we apply the division lemma to 406 and 3, to get
406 = 3 x 135 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 406 is 1
Notice that 1 = HCF(3,1) = HCF(406,3) .
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 609, 723, 406?
Answer: HCF of 609, 723, 406 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 609, 723, 406 using Euclid's Algorithm?
Answer: For arbitrary numbers 609, 723, 406 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
