HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 6218 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 493, 6218 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 493, 6218 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 493, 6218 is 1.

HCF(493, 6218) = 1

Highest common factor (HCF) of 493, 6218 is 1.

Highest Common Factor of 493,6218 using Euclid's algorithm

Highest Common Factor of 493,6218 is 1

Step 1: Since 6218 > 493, we apply the division lemma to 6218 and 493, to get

6218 = 493 x 12 + 302

Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 302 and 493, to get

493 = 302 x 1 + 191

Step 3: We consider the new divisor 302 and the new remainder 191, and apply the division lemma to get

302 = 191 x 1 + 111

We consider the new divisor 191 and the new remainder 111,and apply the division lemma to get

191 = 111 x 1 + 80

We consider the new divisor 111 and the new remainder 80,and apply the division lemma to get

111 = 80 x 1 + 31

We consider the new divisor 80 and the new remainder 31,and apply the division lemma to get

80 = 31 x 2 + 18

We consider the new divisor 31 and the new remainder 18,and apply the division lemma to get

31 = 18 x 1 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 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 493 and 6218 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(31,18) = HCF(80,31) = HCF(111,80) = HCF(191,111) = HCF(302,191) = HCF(493,302) = HCF(6218,493) .
