HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 510, 691, 304 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 510, 691, 304 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 510, 691, 304 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 510, 691, 304 is 1.
HCF(510, 691, 304) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 510, 691, 304 is 1.
Step 1: Since 691 > 510, we apply the division lemma to 691 and 510, to get
691 = 510 x 1 + 181
Step 2: Since the reminder 510 ≠ 0, we apply division lemma to 181 and 510, to get
510 = 181 x 2 + 148
Step 3: We consider the new divisor 181 and the new remainder 148, and apply the division lemma to get
181 = 148 x 1 + 33
We consider the new divisor 148 and the new remainder 33,and apply the division lemma to get
148 = 33 x 4 + 16
We consider the new divisor 33 and the new remainder 16,and apply the division lemma to get
33 = 16 x 2 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 510 and 691 is 1
Notice that 1 = HCF(16,1) = HCF(33,16) = HCF(148,33) = HCF(181,148) = HCF(510,181) = HCF(691,510) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 304 > 1, we apply the division lemma to 304 and 1, to get
304 = 1 x 304 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 304 is 1
Notice that 1 = HCF(304,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 510, 691, 304?
Answer: HCF of 510, 691, 304 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 510, 691, 304 using Euclid's Algorithm?
Answer: For arbitrary numbers 510, 691, 304 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
