HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 864, 341, 391 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 864, 341, 391 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 864, 341, 391 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 864, 341, 391 is 1.

HCF(864, 341, 391) = 1

Highest common factor (HCF) of 864, 341, 391 is 1.

Highest Common Factor of 864,341,391 using Euclid's algorithm

Highest Common Factor of 864,341,391 is 1

Step 1: Since 864 > 341, we apply the division lemma to 864 and 341, to get

864 = 341 x 2 + 182

Step 2: Since the reminder 341 ≠ 0, we apply division lemma to 182 and 341, to get

341 = 182 x 1 + 159

Step 3: We consider the new divisor 182 and the new remainder 159, and apply the division lemma to get

182 = 159 x 1 + 23

We consider the new divisor 159 and the new remainder 23,and apply the division lemma to get

159 = 23 x 6 + 21

We consider the new divisor 23 and the new remainder 21,and apply the division lemma to get

23 = 21 x 1 + 2

We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get

21 = 2 x 10 + 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 864 and 341 is 1

Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(23,21) = HCF(159,23) = HCF(182,159) = HCF(341,182) = HCF(864,341) .

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

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

391 = 1 x 391 + 0

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

Notice that 1 = HCF(391,1) .
