HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 430, 518, 339 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 430, 518, 339 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 636, 430, 518, 339 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 636, 430, 518, 339 is 1.
HCF(636, 430, 518, 339) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 636, 430, 518, 339 is 1.
Step 1: Since 636 > 430, we apply the division lemma to 636 and 430, to get
636 = 430 x 1 + 206
Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 206 and 430, to get
430 = 206 x 2 + 18
Step 3: We consider the new divisor 206 and the new remainder 18, and apply the division lemma to get
206 = 18 x 11 + 8
We consider the new divisor 18 and the new remainder 8,and apply the division lemma to get
18 = 8 x 2 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 636 and 430 is 2
Notice that 2 = HCF(8,2) = HCF(18,8) = HCF(206,18) = HCF(430,206) = HCF(636,430) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 518 > 2, we apply the division lemma to 518 and 2, to get
518 = 2 x 259 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 518 is 2
Notice that 2 = HCF(518,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 339 > 2, we apply the division lemma to 339 and 2, to get
339 = 2 x 169 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 339 is 1
Notice that 1 = HCF(2,1) = HCF(339,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 636, 430, 518, 339?
Answer: HCF of 636, 430, 518, 339 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 636, 430, 518, 339 using Euclid's Algorithm?
Answer: For arbitrary numbers 636, 430, 518, 339 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
