HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 329, 397, 489 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 329, 397, 489 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, 397, 489 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, 397, 489 is 1.

HCF(329, 397, 489) = 1

Highest common factor (HCF) of 329, 397, 489 is 1.

Highest Common Factor of 329,397,489 using Euclid's algorithm

Highest Common Factor of 329,397,489 is 1

Step 1: Since 397 > 329, we apply the division lemma to 397 and 329, to get

397 = 329 x 1 + 68

Step 2: Since the reminder 329 ≠ 0, we apply division lemma to 68 and 329, to get

329 = 68 x 4 + 57

Step 3: We consider the new divisor 68 and the new remainder 57, and apply the division lemma to get

68 = 57 x 1 + 11

We consider the new divisor 57 and the new remainder 11,and apply the division lemma to get

57 = 11 x 5 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 397 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(57,11) = HCF(68,57) = HCF(329,68) = HCF(397,329) .

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

Step 1: Since 489 > 1, we apply the division lemma to 489 and 1, to get

489 = 1 x 489 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 489 is 1

Notice that 1 = HCF(489,1) .
