HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 235, 905, 456 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 235, 905, 456 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 235, 905, 456 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 235, 905, 456 is 1.
HCF(235, 905, 456) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 235, 905, 456 is 1.
Step 1: Since 905 > 235, we apply the division lemma to 905 and 235, to get
905 = 235 x 3 + 200
Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 200 and 235, to get
235 = 200 x 1 + 35
Step 3: We consider the new divisor 200 and the new remainder 35, and apply the division lemma to get
200 = 35 x 5 + 25
We consider the new divisor 35 and the new remainder 25,and apply the division lemma to get
35 = 25 x 1 + 10
We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get
25 = 10 x 2 + 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 235 and 905 is 5
Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(35,25) = HCF(200,35) = HCF(235,200) = HCF(905,235) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 456 > 5, we apply the division lemma to 456 and 5, to get
456 = 5 x 91 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 456 is 1
Notice that 1 = HCF(5,1) = HCF(456,5) .
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 235, 905, 456?
Answer: HCF of 235, 905, 456 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 235, 905, 456 using Euclid's Algorithm?
Answer: For arbitrary numbers 235, 905, 456 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
