HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 232, 786, 391 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 232, 786, 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 232, 786, 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 232, 786, 391 is 1.

HCF(232, 786, 391) = 1

Highest common factor (HCF) of 232, 786, 391 is 1.

Highest Common Factor of 232,786,391 using Euclid's algorithm

Highest Common Factor of 232,786,391 is 1

Step 1: Since 786 > 232, we apply the division lemma to 786 and 232, to get

786 = 232 x 3 + 90

Step 2: Since the reminder 232 ≠ 0, we apply division lemma to 90 and 232, to get

232 = 90 x 2 + 52

Step 3: We consider the new divisor 90 and the new remainder 52, and apply the division lemma to get

90 = 52 x 1 + 38

We consider the new divisor 52 and the new remainder 38,and apply the division lemma to get

52 = 38 x 1 + 14

We consider the new divisor 38 and the new remainder 14,and apply the division lemma to get

38 = 14 x 2 + 10

We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get

14 = 10 x 1 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 232 and 786 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(38,14) = HCF(52,38) = HCF(90,52) = HCF(232,90) = HCF(786,232) .

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

Step 1: Since 391 > 2, we apply the division lemma to 391 and 2, to get

391 = 2 x 195 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 391 is 1

Notice that 1 = HCF(2,1) = HCF(391,2) .
