HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 423, 295 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 489, 423, 295 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, 423, 295 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, 423, 295 is 1.

HCF(489, 423, 295) = 1

HCF of 489, 423, 295 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 489, 423, 295 is 1.

Highest Common Factor of 489,423,295 using Euclid's algorithm

Highest Common Factor of 489,423,295 is 1

Step 1: Since 489 > 423, we apply the division lemma to 489 and 423, to get

489 = 423 x 1 + 66

Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 66 and 423, to get

423 = 66 x 6 + 27

Step 3: We consider the new divisor 66 and the new remainder 27, and apply the division lemma to get

66 = 27 x 2 + 12

We consider the new divisor 27 and the new remainder 12,and apply the division lemma to get

27 = 12 x 2 + 3

We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 489 and 423 is 3

Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(66,27) = HCF(423,66) = HCF(489,423) .

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

Step 1: Since 295 > 3, we apply the division lemma to 295 and 3, to get

295 = 3 x 98 + 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 295 is 1

Notice that 1 = HCF(3,1) = HCF(295,3) .
