HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 387, 265 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 387, 265 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 387, 265 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 387, 265 is 1.
HCF(387, 265) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 387, 265 is 1.
Step 1: Since 387 > 265, we apply the division lemma to 387 and 265, to get
387 = 265 x 1 + 122
Step 2: Since the reminder 265 ≠ 0, we apply division lemma to 122 and 265, to get
265 = 122 x 2 + 21
Step 3: We consider the new divisor 122 and the new remainder 21, and apply the division lemma to get
122 = 21 x 5 + 17
We consider the new divisor 21 and the new remainder 17,and apply the division lemma to get
21 = 17 x 1 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
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 387 and 265 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(21,17) = HCF(122,21) = HCF(265,122) = HCF(387,265) .
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 387, 265?
Answer: HCF of 387, 265 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 387, 265 using Euclid's Algorithm?
Answer: For arbitrary numbers 387, 265 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
