HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 259, 101 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 259, 101 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 259, 101 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 259, 101 is 1.

HCF(259, 101) = 1

Highest common factor (HCF) of 259, 101 is 1.

Highest Common Factor of 259,101 using Euclid's algorithm

Highest Common Factor of 259,101 is 1

Step 1: Since 259 > 101, we apply the division lemma to 259 and 101, to get

259 = 101 x 2 + 57

Step 2: Since the reminder 101 ≠ 0, we apply division lemma to 57 and 101, to get

101 = 57 x 1 + 44

Step 3: We consider the new divisor 57 and the new remainder 44, and apply the division lemma to get

57 = 44 x 1 + 13

We consider the new divisor 44 and the new remainder 13,and apply the division lemma to get

44 = 13 x 3 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 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 259 and 101 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(44,13) = HCF(57,44) = HCF(101,57) = HCF(259,101) .
