HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 66, 55, 327 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 66, 55, 327 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 66, 55, 327 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 66, 55, 327 is 1.

HCF(66, 55, 327) = 1

HCF of 66, 55, 327 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 66, 55, 327 is 1.

Highest Common Factor of 66,55,327 using Euclid's algorithm

Highest Common Factor of 66,55,327 is 1

Step 1: Since 66 > 55, we apply the division lemma to 66 and 55, to get

66 = 55 x 1 + 11

Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 11 and 55, to get

55 = 11 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 66 and 55 is 11

Notice that 11 = HCF(55,11) = HCF(66,55) .

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

Step 1: Since 327 > 11, we apply the division lemma to 327 and 11, to get

327 = 11 x 29 + 8

Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 8 and 11, to get

11 = 8 x 1 + 3

Step 3: We consider the new divisor 8 and the new remainder 3, and apply the division lemma to get

8 = 3 x 2 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 11 and 327 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(327,11) .
