HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 205, 305 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 205, 305 is 5 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 205, 305 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 205, 305 is 5.
HCF(205, 305) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 205, 305 is 5.
Step 1: Since 305 > 205, we apply the division lemma to 305 and 205, to get
305 = 205 x 1 + 100
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 100 and 205, to get
205 = 100 x 2 + 5
Step 3: We consider the new divisor 100 and the new remainder 5, and apply the division lemma to get
100 = 5 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 205 and 305 is 5
Notice that 5 = HCF(100,5) = HCF(205,100) = HCF(305,205) .
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 205, 305?
Answer: HCF of 205, 305 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 205, 305 using Euclid's Algorithm?
Answer: For arbitrary numbers 205, 305 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
