HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 914, 489 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 914, 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 914, 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 914, 489 is 1.

HCF(914, 489) = 1

Highest common factor (HCF) of 914, 489 is 1.

Highest Common Factor of 914,489 using Euclid's algorithm

Highest Common Factor of 914,489 is 1

Step 1: Since 914 > 489, we apply the division lemma to 914 and 489, to get

914 = 489 x 1 + 425

Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 425 and 489, to get

489 = 425 x 1 + 64

Step 3: We consider the new divisor 425 and the new remainder 64, and apply the division lemma to get

425 = 64 x 6 + 41

We consider the new divisor 64 and the new remainder 41,and apply the division lemma to get

64 = 41 x 1 + 23

We consider the new divisor 41 and the new remainder 23,and apply the division lemma to get

41 = 23 x 1 + 18

We consider the new divisor 23 and the new remainder 18,and apply the division lemma to get

23 = 18 x 1 + 5

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 914 and 489 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(23,18) = HCF(41,23) = HCF(64,41) = HCF(425,64) = HCF(489,425) = HCF(914,489) .
