HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 383, 646, 329 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 383, 646, 329 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 383, 646, 329 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 383, 646, 329 is 1.

HCF(383, 646, 329) = 1

Highest common factor (HCF) of 383, 646, 329 is 1.

Highest Common Factor of 383,646,329 using Euclid's algorithm

Highest Common Factor of 383,646,329 is 1

Step 1: Since 646 > 383, we apply the division lemma to 646 and 383, to get

646 = 383 x 1 + 263

Step 2: Since the reminder 383 ≠ 0, we apply division lemma to 263 and 383, to get

383 = 263 x 1 + 120

Step 3: We consider the new divisor 263 and the new remainder 120, and apply the division lemma to get

263 = 120 x 2 + 23

We consider the new divisor 120 and the new remainder 23,and apply the division lemma to get

120 = 23 x 5 + 5

We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get

23 = 5 x 4 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 383 and 646 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(120,23) = HCF(263,120) = HCF(383,263) = HCF(646,383) .

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

Step 1: Since 329 > 1, we apply the division lemma to 329 and 1, to get

329 = 1 x 329 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 329 is 1

Notice that 1 = HCF(329,1) .
