HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 644, 792, 585 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 644, 792, 585 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 644, 792, 585 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 644, 792, 585 is 1.
HCF(644, 792, 585) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 644, 792, 585 is 1.
Step 1: Since 792 > 644, we apply the division lemma to 792 and 644, to get
792 = 644 x 1 + 148
Step 2: Since the reminder 644 ≠ 0, we apply division lemma to 148 and 644, to get
644 = 148 x 4 + 52
Step 3: We consider the new divisor 148 and the new remainder 52, and apply the division lemma to get
148 = 52 x 2 + 44
We consider the new divisor 52 and the new remainder 44,and apply the division lemma to get
52 = 44 x 1 + 8
We consider the new divisor 44 and the new remainder 8,and apply the division lemma to get
44 = 8 x 5 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 644 and 792 is 4
Notice that 4 = HCF(8,4) = HCF(44,8) = HCF(52,44) = HCF(148,52) = HCF(644,148) = HCF(792,644) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 585 > 4, we apply the division lemma to 585 and 4, to get
585 = 4 x 146 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 585 is 1
Notice that 1 = HCF(4,1) = HCF(585,4) .
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 644, 792, 585?
Answer: HCF of 644, 792, 585 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 644, 792, 585 using Euclid's Algorithm?
Answer: For arbitrary numbers 644, 792, 585 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
