HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 729, 986, 805 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 729, 986, 805 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 729, 986, 805 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 729, 986, 805 is 1.

HCF(729, 986, 805) = 1

HCF of 729, 986, 805 using Euclid's algorithm

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

Highest common factor (HCF) of 729, 986, 805 is 1.

Highest Common Factor of 729,986,805 using Euclid's algorithm

Highest Common Factor of 729,986,805 is 1

Step 1: Since 986 > 729, we apply the division lemma to 986 and 729, to get

986 = 729 x 1 + 257

Step 2: Since the reminder 729 ≠ 0, we apply division lemma to 257 and 729, to get

729 = 257 x 2 + 215

Step 3: We consider the new divisor 257 and the new remainder 215, and apply the division lemma to get

257 = 215 x 1 + 42

We consider the new divisor 215 and the new remainder 42,and apply the division lemma to get

215 = 42 x 5 + 5

We consider the new divisor 42 and the new remainder 5,and apply the division lemma to get

42 = 5 x 8 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 729 and 986 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(42,5) = HCF(215,42) = HCF(257,215) = HCF(729,257) = HCF(986,729) .

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

Step 1: Since 805 > 1, we apply the division lemma to 805 and 1, to get

805 = 1 x 805 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 805 is 1

Notice that 1 = HCF(805,1) .
