HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 483, 243, 514, 636 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 483, 243, 514, 636 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 483, 243, 514, 636 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 483, 243, 514, 636 is 1.
HCF(483, 243, 514, 636) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 483, 243, 514, 636 is 1.
Step 1: Since 483 > 243, we apply the division lemma to 483 and 243, to get
483 = 243 x 1 + 240
Step 2: Since the reminder 243 ≠ 0, we apply division lemma to 240 and 243, to get
243 = 240 x 1 + 3
Step 3: We consider the new divisor 240 and the new remainder 3, and apply the division lemma to get
240 = 3 x 80 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 483 and 243 is 3
Notice that 3 = HCF(240,3) = HCF(243,240) = HCF(483,243) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 514 > 3, we apply the division lemma to 514 and 3, to get
514 = 3 x 171 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 514 is 1
Notice that 1 = HCF(3,1) = HCF(514,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 636 > 1, we apply the division lemma to 636 and 1, to get
636 = 1 x 636 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 636 is 1
Notice that 1 = HCF(636,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 483, 243, 514, 636?
Answer: HCF of 483, 243, 514, 636 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 483, 243, 514, 636 using Euclid's Algorithm?
Answer: For arbitrary numbers 483, 243, 514, 636 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
