HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 391, 8095 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 391, 8095 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 391, 8095 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 391, 8095 is 1.

HCF(391, 8095) = 1

Highest Common Factor of 391,8095 using Euclid's algorithm

Highest Common Factor of 391,8095 is 1

Step 1: Since 8095 > 391, we apply the division lemma to 8095 and 391, to get

8095 = 391 x 20 + 275

Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 275 and 391, to get

391 = 275 x 1 + 116

Step 3: We consider the new divisor 275 and the new remainder 116, and apply the division lemma to get

275 = 116 x 2 + 43

We consider the new divisor 116 and the new remainder 43,and apply the division lemma to get

116 = 43 x 2 + 30

We consider the new divisor 43 and the new remainder 30,and apply the division lemma to get

43 = 30 x 1 + 13

We consider the new divisor 30 and the new remainder 13,and apply the division lemma to get

30 = 13 x 2 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 391 and 8095 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(30,13) = HCF(43,30) = HCF(116,43) = HCF(275,116) = HCF(391,275) = HCF(8095,391) .
