HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 804, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 511, 804, 457 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 511, 804, 457 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 511, 804, 457 is 1.
HCF(511, 804, 457) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 511, 804, 457 is 1.
Step 1: Since 804 > 511, we apply the division lemma to 804 and 511, to get
804 = 511 x 1 + 293
Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 293 and 511, to get
511 = 293 x 1 + 218
Step 3: We consider the new divisor 293 and the new remainder 218, and apply the division lemma to get
293 = 218 x 1 + 75
We consider the new divisor 218 and the new remainder 75,and apply the division lemma to get
218 = 75 x 2 + 68
We consider the new divisor 75 and the new remainder 68,and apply the division lemma to get
75 = 68 x 1 + 7
We consider the new divisor 68 and the new remainder 7,and apply the division lemma to get
68 = 7 x 9 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 511 and 804 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(68,7) = HCF(75,68) = HCF(218,75) = HCF(293,218) = HCF(511,293) = HCF(804,511) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 457 > 1, we apply the division lemma to 457 and 1, to get
457 = 1 x 457 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 457 is 1
Notice that 1 = HCF(457,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 511, 804, 457?
Answer: HCF of 511, 804, 457 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 511, 804, 457 using Euclid's Algorithm?
Answer: For arbitrary numbers 511, 804, 457 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
