HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 544, 47 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 315, 544, 47 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 315, 544, 47 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 315, 544, 47 is 1.
HCF(315, 544, 47) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 315, 544, 47 is 1.
Step 1: Since 544 > 315, we apply the division lemma to 544 and 315, to get
544 = 315 x 1 + 229
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 229 and 315, to get
315 = 229 x 1 + 86
Step 3: We consider the new divisor 229 and the new remainder 86, and apply the division lemma to get
229 = 86 x 2 + 57
We consider the new divisor 86 and the new remainder 57,and apply the division lemma to get
86 = 57 x 1 + 29
We consider the new divisor 57 and the new remainder 29,and apply the division lemma to get
57 = 29 x 1 + 28
We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get
29 = 28 x 1 + 1
We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 315 and 544 is 1
Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(57,29) = HCF(86,57) = HCF(229,86) = HCF(315,229) = HCF(544,315) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 47 > 1, we apply the division lemma to 47 and 1, to get
47 = 1 x 47 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 47 is 1
Notice that 1 = HCF(47,1) .
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 315, 544, 47?
Answer: HCF of 315, 544, 47 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 315, 544, 47 using Euclid's Algorithm?
Answer: For arbitrary numbers 315, 544, 47 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
