HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 387, 866, 80 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 387, 866, 80 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 387, 866, 80 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 387, 866, 80 is 1.

HCF(387, 866, 80) = 1

Highest common factor (HCF) of 387, 866, 80 is 1.

Highest Common Factor of 387,866,80 using Euclid's algorithm

Highest Common Factor of 387,866,80 is 1

Step 1: Since 866 > 387, we apply the division lemma to 866 and 387, to get

866 = 387 x 2 + 92

Step 2: Since the reminder 387 ≠ 0, we apply division lemma to 92 and 387, to get

387 = 92 x 4 + 19

Step 3: We consider the new divisor 92 and the new remainder 19, and apply the division lemma to get

92 = 19 x 4 + 16

We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get

19 = 16 x 1 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 387 and 866 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(92,19) = HCF(387,92) = HCF(866,387) .

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

Step 1: Since 80 > 1, we apply the division lemma to 80 and 1, to get

80 = 1 x 80 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 80 is 1

Notice that 1 = HCF(80,1) .
