HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 75, 195, 326 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 75, 195, 326 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, 195, 326 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, 195, 326 is 1.

HCF(75, 195, 326) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 75, 195, 326 is 1.

Highest Common Factor of 75,195,326 using Euclid's algorithm

Highest Common Factor of 75,195,326 is 1

Step 1: Since 195 > 75, we apply the division lemma to 195 and 75, to get

195 = 75 x 2 + 45

Step 2: Since the reminder 75 ≠ 0, we apply division lemma to 45 and 75, to get

75 = 45 x 1 + 30

Step 3: We consider the new divisor 45 and the new remainder 30, and apply the division lemma to get

45 = 30 x 1 + 15

We consider the new divisor 30 and the new remainder 15, and apply the division lemma to get

30 = 15 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 75 and 195 is 15

Notice that 15 = HCF(30,15) = HCF(45,30) = HCF(75,45) = HCF(195,75) .

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

Step 1: Since 326 > 15, we apply the division lemma to 326 and 15, to get

326 = 15 x 21 + 11

Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 11 and 15, to get

15 = 11 x 1 + 4

Step 3: We consider the new divisor 11 and the new remainder 4, and apply the division lemma to get

11 = 4 x 2 + 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 15 and 326 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(326,15) .
