HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 611, 317, 66 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 611, 317, 66 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 611, 317, 66 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 611, 317, 66 is 1.

HCF(611, 317, 66) = 1

Highest common factor (HCF) of 611, 317, 66 is 1.

Highest Common Factor of 611,317,66 using Euclid's algorithm

Highest Common Factor of 611,317,66 is 1

Step 1: Since 611 > 317, we apply the division lemma to 611 and 317, to get

611 = 317 x 1 + 294

Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 294 and 317, to get

317 = 294 x 1 + 23

Step 3: We consider the new divisor 294 and the new remainder 23, and apply the division lemma to get

294 = 23 x 12 + 18

We consider the new divisor 23 and the new remainder 18,and apply the division lemma to get

23 = 18 x 1 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 611 and 317 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(23,18) = HCF(294,23) = HCF(317,294) = HCF(611,317) .

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

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

66 = 1 x 66 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 66 is 1

Notice that 1 = HCF(66,1) .
