HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 259, 358 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 489, 259, 358 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, 259, 358 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, 259, 358 is 1.

HCF(489, 259, 358) = 1

HCF of 489, 259, 358 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, 259, 358 is 1.

Highest Common Factor of 489,259,358 using Euclid's algorithm

Highest Common Factor of 489,259,358 is 1

Step 1: Since 489 > 259, we apply the division lemma to 489 and 259, to get

489 = 259 x 1 + 230

Step 2: Since the reminder 259 ≠ 0, we apply division lemma to 230 and 259, to get

259 = 230 x 1 + 29

Step 3: We consider the new divisor 230 and the new remainder 29, and apply the division lemma to get

230 = 29 x 7 + 27

We consider the new divisor 29 and the new remainder 27,and apply the division lemma to get

29 = 27 x 1 + 2

We consider the new divisor 27 and the new remainder 2,and apply the division lemma to get

27 = 2 x 13 + 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 259 is 1

Notice that 1 = HCF(2,1) = HCF(27,2) = HCF(29,27) = HCF(230,29) = HCF(259,230) = HCF(489,259) .

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

Step 1: Since 358 > 1, we apply the division lemma to 358 and 1, to get

358 = 1 x 358 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 358 is 1

Notice that 1 = HCF(358,1) .
