HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 478, 259 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 478, 259 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 478, 259 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 478, 259 is 1.

HCF(478, 259) = 1

HCF of 478, 259 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 478, 259 is 1.

Highest Common Factor of 478,259 using Euclid's algorithm

Highest Common Factor of 478,259 is 1

Step 1: Since 478 > 259, we apply the division lemma to 478 and 259, to get

478 = 259 x 1 + 219

Step 2: Since the reminder 259 ≠ 0, we apply division lemma to 219 and 259, to get

259 = 219 x 1 + 40

Step 3: We consider the new divisor 219 and the new remainder 40, and apply the division lemma to get

219 = 40 x 5 + 19

We consider the new divisor 40 and the new remainder 19,and apply the division lemma to get

40 = 19 x 2 + 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 478 and 259 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(40,19) = HCF(219,40) = HCF(259,219) = HCF(478,259) .
