HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 54, 189, 193 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 54, 189, 193 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 54, 189, 193 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 54, 189, 193 is 1.

HCF(54, 189, 193) = 1

HCF of 54, 189, 193 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 54, 189, 193 is 1.

Highest Common Factor of 54,189,193 using Euclid's algorithm

Highest Common Factor of 54,189,193 is 1

Step 1: Since 189 > 54, we apply the division lemma to 189 and 54, to get

189 = 54 x 3 + 27

Step 2: Since the reminder 54 ≠ 0, we apply division lemma to 27 and 54, to get

54 = 27 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 54 and 189 is 27

Notice that 27 = HCF(54,27) = HCF(189,54) .


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

Step 1: Since 193 > 27, we apply the division lemma to 193 and 27, to get

193 = 27 x 7 + 4

Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 4 and 27, to get

27 = 4 x 6 + 3

Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 27 and 193 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(27,4) = HCF(193,27) .
