HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 384, 855, 424 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 384, 855, 424 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 384, 855, 424 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 384, 855, 424 is 1.

HCF(384, 855, 424) = 1

Highest common factor (HCF) of 384, 855, 424 is 1.

Highest Common Factor of 384,855,424 using Euclid's algorithm

Highest Common Factor of 384,855,424 is 1

Step 1: Since 855 > 384, we apply the division lemma to 855 and 384, to get

855 = 384 x 2 + 87

Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 87 and 384, to get

384 = 87 x 4 + 36

Step 3: We consider the new divisor 87 and the new remainder 36, and apply the division lemma to get

87 = 36 x 2 + 15

We consider the new divisor 36 and the new remainder 15,and apply the division lemma to get

36 = 15 x 2 + 6

We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 384 and 855 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(36,15) = HCF(87,36) = HCF(384,87) = HCF(855,384) .

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

Step 1: Since 424 > 3, we apply the division lemma to 424 and 3, to get

424 = 3 x 141 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 424 is 1

Notice that 1 = HCF(3,1) = HCF(424,3) .
