HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 925, 395, 269 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 925, 395, 269 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 925, 395, 269 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 925, 395, 269 is 1.
HCF(925, 395, 269) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 925, 395, 269 is 1.
Step 1: Since 925 > 395, we apply the division lemma to 925 and 395, to get
925 = 395 x 2 + 135
Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 135 and 395, to get
395 = 135 x 2 + 125
Step 3: We consider the new divisor 135 and the new remainder 125, and apply the division lemma to get
135 = 125 x 1 + 10
We consider the new divisor 125 and the new remainder 10,and apply the division lemma to get
125 = 10 x 12 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 925 and 395 is 5
Notice that 5 = HCF(10,5) = HCF(125,10) = HCF(135,125) = HCF(395,135) = HCF(925,395) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 269 > 5, we apply the division lemma to 269 and 5, to get
269 = 5 x 53 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma 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 5 and 269 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(269,5) .
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 925, 395, 269?
Answer: HCF of 925, 395, 269 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 925, 395, 269 using Euclid's Algorithm?
Answer: For arbitrary numbers 925, 395, 269 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
