HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 311, 981 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 869, 311, 981 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 869, 311, 981 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 869, 311, 981 is 1.

HCF(869, 311, 981) = 1

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

HCF of:

Highest common factor (HCF) of 869, 311, 981 is 1.

Highest Common Factor of 869,311,981 using Euclid's algorithm

Highest Common Factor of 869,311,981 is 1

Step 1: Since 869 > 311, we apply the division lemma to 869 and 311, to get

869 = 311 x 2 + 247

Step 2: Since the reminder 311 ≠ 0, we apply division lemma to 247 and 311, to get

311 = 247 x 1 + 64

Step 3: We consider the new divisor 247 and the new remainder 64, and apply the division lemma to get

247 = 64 x 3 + 55

We consider the new divisor 64 and the new remainder 55,and apply the division lemma to get

64 = 55 x 1 + 9

We consider the new divisor 55 and the new remainder 9,and apply the division lemma to get

55 = 9 x 6 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 869 and 311 is 1

Notice that 1 = HCF(9,1) = HCF(55,9) = HCF(64,55) = HCF(247,64) = HCF(311,247) = HCF(869,311) .

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

Step 1: Since 981 > 1, we apply the division lemma to 981 and 1, to get

981 = 1 x 981 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 981 is 1

Notice that 1 = HCF(981,1) .
