HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 218, 595, 687 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 218, 595, 687 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 218, 595, 687 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 218, 595, 687 is 1.

HCF(218, 595, 687) = 1

HCF of 218, 595, 687 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 218, 595, 687 is 1.

Highest Common Factor of 218,595,687 using Euclid's algorithm

Highest Common Factor of 218,595,687 is 1

Step 1: Since 595 > 218, we apply the division lemma to 595 and 218, to get

595 = 218 x 2 + 159

Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 159 and 218, to get

218 = 159 x 1 + 59

Step 3: We consider the new divisor 159 and the new remainder 59, and apply the division lemma to get

159 = 59 x 2 + 41

We consider the new divisor 59 and the new remainder 41,and apply the division lemma to get

59 = 41 x 1 + 18

We consider the new divisor 41 and the new remainder 18,and apply the division lemma to get

41 = 18 x 2 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 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 218 and 595 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(41,18) = HCF(59,41) = HCF(159,59) = HCF(218,159) = HCF(595,218) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 687 > 1, we apply the division lemma to 687 and 1, to get

687 = 1 x 687 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 687 is 1

Notice that 1 = HCF(687,1) .
