HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 81, 866, 318, 197 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 81, 866, 318, 197 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 81, 866, 318, 197 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 81, 866, 318, 197 is 1.

HCF(81, 866, 318, 197) = 1

Highest common factor (HCF) of 81, 866, 318, 197 is 1.

Highest Common Factor of 81,866,318,197 using Euclid's algorithm

Highest Common Factor of 81,866,318,197 is 1

Step 1: Since 866 > 81, we apply the division lemma to 866 and 81, to get

866 = 81 x 10 + 56

Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 56 and 81, to get

81 = 56 x 1 + 25

Step 3: We consider the new divisor 56 and the new remainder 25, and apply the division lemma to get

56 = 25 x 2 + 6

We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get

25 = 6 x 4 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 81 and 866 is 1

Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(56,25) = HCF(81,56) = HCF(866,81) .


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

Step 1: Since 318 > 1, we apply the division lemma to 318 and 1, to get

318 = 1 x 318 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 318 is 1

Notice that 1 = HCF(318,1) .


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

Step 1: Since 197 > 1, we apply the division lemma to 197 and 1, to get

197 = 1 x 197 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 197 is 1

Notice that 1 = HCF(197,1) .
