HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 203, 261, 577 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 203, 261, 577 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 203, 261, 577 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 203, 261, 577 is 1.
HCF(203, 261, 577) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 203, 261, 577 is 1.
Step 1: Since 261 > 203, we apply the division lemma to 261 and 203, to get
261 = 203 x 1 + 58
Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 58 and 203, to get
203 = 58 x 3 + 29
Step 3: We consider the new divisor 58 and the new remainder 29, and apply the division lemma to get
58 = 29 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 29, the HCF of 203 and 261 is 29
Notice that 29 = HCF(58,29) = HCF(203,58) = HCF(261,203) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 577 > 29, we apply the division lemma to 577 and 29, to get
577 = 29 x 19 + 26
Step 2: Since the reminder 29 ≠ 0, we apply division lemma to 26 and 29, to get
29 = 26 x 1 + 3
Step 3: We consider the new divisor 26 and the new remainder 3, and apply the division lemma to get
26 = 3 x 8 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 29 and 577 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(29,26) = HCF(577,29) .
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 203, 261, 577?
Answer: HCF of 203, 261, 577 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 203, 261, 577 using Euclid's Algorithm?
Answer: For arbitrary numbers 203, 261, 577 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
