HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 513, 800, 93 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 513, 800, 93 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 513, 800, 93 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 513, 800, 93 is 1.
HCF(513, 800, 93) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 513, 800, 93 is 1.
Step 1: Since 800 > 513, we apply the division lemma to 800 and 513, to get
800 = 513 x 1 + 287
Step 2: Since the reminder 513 ≠ 0, we apply division lemma to 287 and 513, to get
513 = 287 x 1 + 226
Step 3: We consider the new divisor 287 and the new remainder 226, and apply the division lemma to get
287 = 226 x 1 + 61
We consider the new divisor 226 and the new remainder 61,and apply the division lemma to get
226 = 61 x 3 + 43
We consider the new divisor 61 and the new remainder 43,and apply the division lemma to get
61 = 43 x 1 + 18
We consider the new divisor 43 and the new remainder 18,and apply the division lemma to get
43 = 18 x 2 + 7
We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get
18 = 7 x 2 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 513 and 800 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(43,18) = HCF(61,43) = HCF(226,61) = HCF(287,226) = HCF(513,287) = HCF(800,513) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 93 > 1, we apply the division lemma to 93 and 1, to get
93 = 1 x 93 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 93 is 1
Notice that 1 = HCF(93,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 513, 800, 93?
Answer: HCF of 513, 800, 93 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 513, 800, 93 using Euclid's Algorithm?
Answer: For arbitrary numbers 513, 800, 93 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
