HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 75, 95, 27 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 75, 95, 27 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 75, 95, 27 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 75, 95, 27 is 1.

HCF(75, 95, 27) = 1

HCF of 75, 95, 27 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 75, 95, 27 is 1.

Highest Common Factor of 75,95,27 using Euclid's algorithm

Highest Common Factor of 75,95,27 is 1

Step 1: Since 95 > 75, we apply the division lemma to 95 and 75, to get

95 = 75 x 1 + 20

Step 2: Since the reminder 75 ≠ 0, we apply division lemma to 20 and 75, to get

75 = 20 x 3 + 15

Step 3: We consider the new divisor 20 and the new remainder 15, and apply the division lemma to get

20 = 15 x 1 + 5

We consider the new divisor 15 and the new remainder 5, and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 75 and 95 is 5

Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(75,20) = HCF(95,75) .

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

Step 1: Since 27 > 5, we apply the division lemma to 27 and 5, to get

27 = 5 x 5 + 2

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get

5 = 2 x 2 + 1

Step 3: 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 5 and 27 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) .
