HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 613, 24 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 489, 613, 24 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, 613, 24 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, 613, 24 is 1.

HCF(489, 613, 24) = 1

HCF of 489, 613, 24 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 489, 613, 24 is 1.

Highest Common Factor of 489,613,24 using Euclid's algorithm

Highest Common Factor of 489,613,24 is 1

Step 1: Since 613 > 489, we apply the division lemma to 613 and 489, to get

613 = 489 x 1 + 124

Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 124 and 489, to get

489 = 124 x 3 + 117

Step 3: We consider the new divisor 124 and the new remainder 117, and apply the division lemma to get

124 = 117 x 1 + 7

We consider the new divisor 117 and the new remainder 7,and apply the division lemma to get

117 = 7 x 16 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 613 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(117,7) = HCF(124,117) = HCF(489,124) = HCF(613,489) .

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

Step 1: Since 24 > 1, we apply the division lemma to 24 and 1, to get

24 = 1 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 24 is 1

Notice that 1 = HCF(24,1) .
