HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 626, 288 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 489, 626, 288 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, 626, 288 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, 626, 288 is 1.

HCF(489, 626, 288) = 1

HCF of 489, 626, 288 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, 626, 288 is 1.

Highest Common Factor of 489,626,288 using Euclid's algorithm

Highest Common Factor of 489,626,288 is 1

Step 1: Since 626 > 489, we apply the division lemma to 626 and 489, to get

626 = 489 x 1 + 137

Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 137 and 489, to get

489 = 137 x 3 + 78

Step 3: We consider the new divisor 137 and the new remainder 78, and apply the division lemma to get

137 = 78 x 1 + 59

We consider the new divisor 78 and the new remainder 59,and apply the division lemma to get

78 = 59 x 1 + 19

We consider the new divisor 59 and the new remainder 19,and apply the division lemma to get

59 = 19 x 3 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 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 489 and 626 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(59,19) = HCF(78,59) = HCF(137,78) = HCF(489,137) = HCF(626,489) .


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

Step 1: Since 288 > 1, we apply the division lemma to 288 and 1, to get

288 = 1 x 288 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 288 is 1

Notice that 1 = HCF(288,1) .
