HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 381, 664, 394 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 381, 664, 394 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, 664, 394 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, 664, 394 is 1.

HCF(381, 664, 394) = 1

Highest common factor (HCF) of 381, 664, 394 is 1.

Highest Common Factor of 381,664,394 using Euclid's algorithm

Highest Common Factor of 381,664,394 is 1

Step 1: Since 664 > 381, we apply the division lemma to 664 and 381, to get

664 = 381 x 1 + 283

Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 283 and 381, to get

381 = 283 x 1 + 98

Step 3: We consider the new divisor 283 and the new remainder 98, and apply the division lemma to get

283 = 98 x 2 + 87

We consider the new divisor 98 and the new remainder 87,and apply the division lemma to get

98 = 87 x 1 + 11

We consider the new divisor 87 and the new remainder 11,and apply the division lemma to get

87 = 11 x 7 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 381 and 664 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(87,11) = HCF(98,87) = HCF(283,98) = HCF(381,283) = HCF(664,381) .

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

Step 1: Since 394 > 1, we apply the division lemma to 394 and 1, to get

394 = 1 x 394 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 394 is 1

Notice that 1 = HCF(394,1) .
