HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 71103 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 398, 71103 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 398, 71103 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 398, 71103 is 1.

HCF(398, 71103) = 1

Highest Common Factor of 398,71103 using Euclid's algorithm

Highest Common Factor of 398,71103 is 1

Step 1: Since 71103 > 398, we apply the division lemma to 71103 and 398, to get

71103 = 398 x 178 + 259

Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 259 and 398, to get

398 = 259 x 1 + 139

Step 3: We consider the new divisor 259 and the new remainder 139, and apply the division lemma to get

259 = 139 x 1 + 120

We consider the new divisor 139 and the new remainder 120,and apply the division lemma to get

139 = 120 x 1 + 19

We consider the new divisor 120 and the new remainder 19,and apply the division lemma to get

120 = 19 x 6 + 6

We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get

19 = 6 x 3 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 398 and 71103 is 1

Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(120,19) = HCF(139,120) = HCF(259,139) = HCF(398,259) = HCF(71103,398) .
