HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 433 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 489, 433 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 489, 433 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 489, 433 is 1.

HCF(489, 433) = 1

Highest common factor (HCF) of 489, 433 is 1.

Highest Common Factor of 489,433 using Euclid's algorithm

Highest Common Factor of 489,433 is 1

Step 1: Since 489 > 433, we apply the division lemma to 489 and 433, to get

489 = 433 x 1 + 56

Step 2: Since the reminder 433 ≠ 0, we apply division lemma to 56 and 433, to get

433 = 56 x 7 + 41

Step 3: We consider the new divisor 56 and the new remainder 41, and apply the division lemma to get

56 = 41 x 1 + 15

We consider the new divisor 41 and the new remainder 15,and apply the division lemma to get

41 = 15 x 2 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 489 and 433 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(41,15) = HCF(56,41) = HCF(433,56) = HCF(489,433) .
