HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 684, 417 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 684, 417 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 684, 417 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 684, 417 is 3.
HCF(684, 417) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 684, 417 is 3.
Step 1: Since 684 > 417, we apply the division lemma to 684 and 417, to get
684 = 417 x 1 + 267
Step 2: Since the reminder 417 ≠ 0, we apply division lemma to 267 and 417, to get
417 = 267 x 1 + 150
Step 3: We consider the new divisor 267 and the new remainder 150, and apply the division lemma to get
267 = 150 x 1 + 117
We consider the new divisor 150 and the new remainder 117,and apply the division lemma to get
150 = 117 x 1 + 33
We consider the new divisor 117 and the new remainder 33,and apply the division lemma to get
117 = 33 x 3 + 18
We consider the new divisor 33 and the new remainder 18,and apply the division lemma to get
33 = 18 x 1 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 684 and 417 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(33,18) = HCF(117,33) = HCF(150,117) = HCF(267,150) = HCF(417,267) = HCF(684,417) .
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 684, 417?
Answer: HCF of 684, 417 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 684, 417 using Euclid's Algorithm?
Answer: For arbitrary numbers 684, 417 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
