HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 381, 910, 388 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 381, 910, 388 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 381, 910, 388 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 381, 910, 388 is 1.

HCF(381, 910, 388) = 1

Highest common factor (HCF) of 381, 910, 388 is 1.

Highest Common Factor of 381,910,388 using Euclid's algorithm

Highest Common Factor of 381,910,388 is 1

Step 1: Since 910 > 381, we apply the division lemma to 910 and 381, to get

910 = 381 x 2 + 148

Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 148 and 381, to get

381 = 148 x 2 + 85

Step 3: We consider the new divisor 148 and the new remainder 85, and apply the division lemma to get

148 = 85 x 1 + 63

We consider the new divisor 85 and the new remainder 63,and apply the division lemma to get

85 = 63 x 1 + 22

We consider the new divisor 63 and the new remainder 22,and apply the division lemma to get

63 = 22 x 2 + 19

We consider the new divisor 22 and the new remainder 19,and apply the division lemma to get

22 = 19 x 1 + 3

We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get

19 = 3 x 6 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 381 and 910 is 1

Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(22,19) = HCF(63,22) = HCF(85,63) = HCF(148,85) = HCF(381,148) = HCF(910,381) .

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

Step 1: Since 388 > 1, we apply the division lemma to 388 and 1, to get

388 = 1 x 388 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 388 is 1

Notice that 1 = HCF(388,1) .
