HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 482, 381 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 838, 482, 381 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 838, 482, 381 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 838, 482, 381 is 1.

HCF(838, 482, 381) = 1

Highest common factor (HCF) of 838, 482, 381 is 1.

Highest Common Factor of 838,482,381 using Euclid's algorithm

Highest Common Factor of 838,482,381 is 1

Step 1: Since 838 > 482, we apply the division lemma to 838 and 482, to get

838 = 482 x 1 + 356

Step 2: Since the reminder 482 ≠ 0, we apply division lemma to 356 and 482, to get

482 = 356 x 1 + 126

Step 3: We consider the new divisor 356 and the new remainder 126, and apply the division lemma to get

356 = 126 x 2 + 104

We consider the new divisor 126 and the new remainder 104,and apply the division lemma to get

126 = 104 x 1 + 22

We consider the new divisor 104 and the new remainder 22,and apply the division lemma to get

104 = 22 x 4 + 16

We consider the new divisor 22 and the new remainder 16,and apply the division lemma to get

22 = 16 x 1 + 6

We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get

16 = 6 x 2 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 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 838 and 482 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(104,22) = HCF(126,104) = HCF(356,126) = HCF(482,356) = HCF(838,482) .

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

Step 1: Since 381 > 2, we apply the division lemma to 381 and 2, to get

381 = 2 x 190 + 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 381 is 1

Notice that 1 = HCF(2,1) = HCF(381,2) .
