HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 518, 654 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 801, 518, 654 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 801, 518, 654 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 801, 518, 654 is 1.
HCF(801, 518, 654) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 801, 518, 654 is 1.
Step 1: Since 801 > 518, we apply the division lemma to 801 and 518, to get
801 = 518 x 1 + 283
Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 283 and 518, to get
518 = 283 x 1 + 235
Step 3: We consider the new divisor 283 and the new remainder 235, and apply the division lemma to get
283 = 235 x 1 + 48
We consider the new divisor 235 and the new remainder 48,and apply the division lemma to get
235 = 48 x 4 + 43
We consider the new divisor 48 and the new remainder 43,and apply the division lemma to get
48 = 43 x 1 + 5
We consider the new divisor 43 and the new remainder 5,and apply the division lemma to get
43 = 5 x 8 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 801 and 518 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(43,5) = HCF(48,43) = HCF(235,48) = HCF(283,235) = HCF(518,283) = HCF(801,518) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 654 > 1, we apply the division lemma to 654 and 1, to get
654 = 1 x 654 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 654 is 1
Notice that 1 = HCF(654,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 801, 518, 654?
Answer: HCF of 801, 518, 654 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 801, 518, 654 using Euclid's Algorithm?
Answer: For arbitrary numbers 801, 518, 654 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
