HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 295, 173, 258 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 295, 173, 258 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 295, 173, 258 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 295, 173, 258 is 1.

HCF(295, 173, 258) = 1

Highest common factor (HCF) of 295, 173, 258 is 1.

Highest Common Factor of 295,173,258 using Euclid's algorithm

Highest Common Factor of 295,173,258 is 1

Step 1: Since 295 > 173, we apply the division lemma to 295 and 173, to get

295 = 173 x 1 + 122

Step 2: Since the reminder 173 ≠ 0, we apply division lemma to 122 and 173, to get

173 = 122 x 1 + 51

Step 3: We consider the new divisor 122 and the new remainder 51, and apply the division lemma to get

122 = 51 x 2 + 20

We consider the new divisor 51 and the new remainder 20,and apply the division lemma to get

51 = 20 x 2 + 11

We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get

20 = 11 x 1 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 295 and 173 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(51,20) = HCF(122,51) = HCF(173,122) = HCF(295,173) .

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

Step 1: Since 258 > 1, we apply the division lemma to 258 and 1, to get

258 = 1 x 258 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 258 is 1

Notice that 1 = HCF(258,1) .
