HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 275, 172, 239 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 275, 172, 239 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 275, 172, 239 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 275, 172, 239 is 1.
HCF(275, 172, 239) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 275, 172, 239 is 1.
Step 1: Since 275 > 172, we apply the division lemma to 275 and 172, to get
275 = 172 x 1 + 103
Step 2: Since the reminder 172 ≠ 0, we apply division lemma to 103 and 172, to get
172 = 103 x 1 + 69
Step 3: We consider the new divisor 103 and the new remainder 69, and apply the division lemma to get
103 = 69 x 1 + 34
We consider the new divisor 69 and the new remainder 34,and apply the division lemma to get
69 = 34 x 2 + 1
We consider the new divisor 34 and the new remainder 1,and apply the division lemma to get
34 = 1 x 34 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 275 and 172 is 1
Notice that 1 = HCF(34,1) = HCF(69,34) = HCF(103,69) = HCF(172,103) = HCF(275,172) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 239 > 1, we apply the division lemma to 239 and 1, to get
239 = 1 x 239 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 239 is 1
Notice that 1 = HCF(239,1) .
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 275, 172, 239?
Answer: HCF of 275, 172, 239 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 275, 172, 239 using Euclid's Algorithm?
Answer: For arbitrary numbers 275, 172, 239 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
