HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 921, 489, 382 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 921, 489, 382 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 921, 489, 382 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 921, 489, 382 is 1.

HCF(921, 489, 382) = 1

Highest common factor (HCF) of 921, 489, 382 is 1.

Highest Common Factor of 921,489,382 using Euclid's algorithm

Highest Common Factor of 921,489,382 is 1

Step 1: Since 921 > 489, we apply the division lemma to 921 and 489, to get

921 = 489 x 1 + 432

Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 432 and 489, to get

489 = 432 x 1 + 57

Step 3: We consider the new divisor 432 and the new remainder 57, and apply the division lemma to get

432 = 57 x 7 + 33

We consider the new divisor 57 and the new remainder 33,and apply the division lemma to get

57 = 33 x 1 + 24

We consider the new divisor 33 and the new remainder 24,and apply the division lemma to get

33 = 24 x 1 + 9

We consider the new divisor 24 and the new remainder 9,and apply the division lemma to get

24 = 9 x 2 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 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 921 and 489 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(33,24) = HCF(57,33) = HCF(432,57) = HCF(489,432) = HCF(921,489) .

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

Step 1: Since 382 > 3, we apply the division lemma to 382 and 3, to get

382 = 3 x 127 + 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 382 is 1

Notice that 1 = HCF(3,1) = HCF(382,3) .
