HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 289, 697 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 812, 289, 697 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 812, 289, 697 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 812, 289, 697 is 1.

HCF(812, 289, 697) = 1

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

HCF of:

Highest common factor (HCF) of 812, 289, 697 is 1.

Highest Common Factor of 812,289,697 using Euclid's algorithm

Highest Common Factor of 812,289,697 is 1

Step 1: Since 812 > 289, we apply the division lemma to 812 and 289, to get

812 = 289 x 2 + 234

Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 234 and 289, to get

289 = 234 x 1 + 55

Step 3: We consider the new divisor 234 and the new remainder 55, and apply the division lemma to get

234 = 55 x 4 + 14

We consider the new divisor 55 and the new remainder 14,and apply the division lemma to get

55 = 14 x 3 + 13

We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get

14 = 13 x 1 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 812 and 289 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(55,14) = HCF(234,55) = HCF(289,234) = HCF(812,289) .

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

Step 1: Since 697 > 1, we apply the division lemma to 697 and 1, to get

697 = 1 x 697 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 697 is 1

Notice that 1 = HCF(697,1) .
