HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 786, 697, 289 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 786, 697, 289 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 786, 697, 289 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 786, 697, 289 is 1.

HCF(786, 697, 289) = 1

HCF of 786, 697, 289 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 786, 697, 289 is 1.

Highest Common Factor of 786,697,289 using Euclid's algorithm

Highest Common Factor of 786,697,289 is 1

Step 1: Since 786 > 697, we apply the division lemma to 786 and 697, to get

786 = 697 x 1 + 89

Step 2: Since the reminder 697 ≠ 0, we apply division lemma to 89 and 697, to get

697 = 89 x 7 + 74

Step 3: We consider the new divisor 89 and the new remainder 74, and apply the division lemma to get

89 = 74 x 1 + 15

We consider the new divisor 74 and the new remainder 15,and apply the division lemma to get

74 = 15 x 4 + 14

We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get

15 = 14 x 1 + 1

We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 786 and 697 is 1

Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(74,15) = HCF(89,74) = HCF(697,89) = HCF(786,697) .

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

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

289 = 1 x 289 + 0

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

Notice that 1 = HCF(289,1) .
