HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 597, 966 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 818, 597, 966 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 818, 597, 966 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 818, 597, 966 is 1.

HCF(818, 597, 966) = 1

HCF of 818, 597, 966 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 818, 597, 966 is 1.

Highest Common Factor of 818,597,966 using Euclid's algorithm

Highest Common Factor of 818,597,966 is 1

Step 1: Since 818 > 597, we apply the division lemma to 818 and 597, to get

818 = 597 x 1 + 221

Step 2: Since the reminder 597 ≠ 0, we apply division lemma to 221 and 597, to get

597 = 221 x 2 + 155

Step 3: We consider the new divisor 221 and the new remainder 155, and apply the division lemma to get

221 = 155 x 1 + 66

We consider the new divisor 155 and the new remainder 66,and apply the division lemma to get

155 = 66 x 2 + 23

We consider the new divisor 66 and the new remainder 23,and apply the division lemma to get

66 = 23 x 2 + 20

We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get

23 = 20 x 1 + 3

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

20 = 3 x 6 + 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 818 and 597 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(66,23) = HCF(155,66) = HCF(221,155) = HCF(597,221) = HCF(818,597) .

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

Step 1: Since 966 > 1, we apply the division lemma to 966 and 1, to get

966 = 1 x 966 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 966 is 1

Notice that 1 = HCF(966,1) .
