HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 843, 57117 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 843, 57117 is 3 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 843, 57117 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 843, 57117 is 3.

HCF(843, 57117) = 3

Highest common factor (HCF) of 843, 57117 is 3.

Highest Common Factor of 843,57117 using Euclid's algorithm

Highest Common Factor of 843,57117 is 3

Step 1: Since 57117 > 843, we apply the division lemma to 57117 and 843, to get

57117 = 843 x 67 + 636

Step 2: Since the reminder 843 ≠ 0, we apply division lemma to 636 and 843, to get

843 = 636 x 1 + 207

Step 3: We consider the new divisor 636 and the new remainder 207, and apply the division lemma to get

636 = 207 x 3 + 15

We consider the new divisor 207 and the new remainder 15,and apply the division lemma to get

207 = 15 x 13 + 12

We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get

15 = 12 x 1 + 3

We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 843 and 57117 is 3

Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(207,15) = HCF(636,207) = HCF(843,636) = HCF(57117,843) .
