HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 259, 309 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 485, 259, 309 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 485, 259, 309 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 485, 259, 309 is 1.

HCF(485, 259, 309) = 1

Highest common factor (HCF) of 485, 259, 309 is 1.

Highest Common Factor of 485,259,309 using Euclid's algorithm

Highest Common Factor of 485,259,309 is 1

Step 1: Since 485 > 259, we apply the division lemma to 485 and 259, to get

485 = 259 x 1 + 226

Step 2: Since the reminder 259 ≠ 0, we apply division lemma to 226 and 259, to get

259 = 226 x 1 + 33

Step 3: We consider the new divisor 226 and the new remainder 33, and apply the division lemma to get

226 = 33 x 6 + 28

We consider the new divisor 33 and the new remainder 28,and apply the division lemma to get

33 = 28 x 1 + 5

We consider the new divisor 28 and the new remainder 5,and apply the division lemma to get

28 = 5 x 5 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 485 and 259 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(28,5) = HCF(33,28) = HCF(226,33) = HCF(259,226) = HCF(485,259) .

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

Step 1: Since 309 > 1, we apply the division lemma to 309 and 1, to get

309 = 1 x 309 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 309 is 1

Notice that 1 = HCF(309,1) .
