HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 82, 459, 854, 819 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 82, 459, 854, 819 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 82, 459, 854, 819 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 82, 459, 854, 819 is 1.
HCF(82, 459, 854, 819) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 82, 459, 854, 819 is 1.
Step 1: Since 459 > 82, we apply the division lemma to 459 and 82, to get
459 = 82 x 5 + 49
Step 2: Since the reminder 82 ≠ 0, we apply division lemma to 49 and 82, to get
82 = 49 x 1 + 33
Step 3: We consider the new divisor 49 and the new remainder 33, and apply the division lemma to get
49 = 33 x 1 + 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 82 and 459 is 1
Notice that 1 = HCF(16,1) = HCF(33,16) = HCF(49,33) = HCF(82,49) = HCF(459,82) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 854 > 1, we apply the division lemma to 854 and 1, to get
854 = 1 x 854 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 854 is 1
Notice that 1 = HCF(854,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 819 > 1, we apply the division lemma to 819 and 1, to get
819 = 1 x 819 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 819 is 1
Notice that 1 = HCF(819,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 82, 459, 854, 819?
Answer: HCF of 82, 459, 854, 819 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 82, 459, 854, 819 using Euclid's Algorithm?
Answer: For arbitrary numbers 82, 459, 854, 819 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
