HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 193, 636, 258 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 193, 636, 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 193, 636, 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 193, 636, 258 is 1.

HCF(193, 636, 258) = 1

HCF of 193, 636, 258 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 193, 636, 258 is 1.

Highest Common Factor of 193,636,258 using Euclid's algorithm

Highest Common Factor of 193,636,258 is 1

Step 1: Since 636 > 193, we apply the division lemma to 636 and 193, to get

636 = 193 x 3 + 57

Step 2: Since the reminder 193 ≠ 0, we apply division lemma to 57 and 193, to get

193 = 57 x 3 + 22

Step 3: We consider the new divisor 57 and the new remainder 22, and apply the division lemma to get

57 = 22 x 2 + 13

We consider the new divisor 22 and the new remainder 13,and apply the division lemma to get

22 = 13 x 1 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 193 and 636 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(57,22) = HCF(193,57) = HCF(636,193) .

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) .
