HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 329, 676, 385 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 329, 676, 385 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 329, 676, 385 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 329, 676, 385 is 1.

HCF(329, 676, 385) = 1

Highest common factor (HCF) of 329, 676, 385 is 1.

Highest Common Factor of 329,676,385 using Euclid's algorithm

Highest Common Factor of 329,676,385 is 1

Step 1: Since 676 > 329, we apply the division lemma to 676 and 329, to get

676 = 329 x 2 + 18

Step 2: Since the reminder 329 ≠ 0, we apply division lemma to 18 and 329, to get

329 = 18 x 18 + 5

Step 3: We consider the new divisor 18 and the new remainder 5, and apply the division lemma to get

18 = 5 x 3 + 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 329 and 676 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(329,18) = HCF(676,329) .

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

Step 1: Since 385 > 1, we apply the division lemma to 385 and 1, to get

385 = 1 x 385 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 385 is 1

Notice that 1 = HCF(385,1) .
