HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 313, 819, 860 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 313, 819, 860 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 313, 819, 860 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 313, 819, 860 is 1.

HCF(313, 819, 860) = 1

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

HCF of:

Highest common factor (HCF) of 313, 819, 860 is 1.

Highest Common Factor of 313,819,860 using Euclid's algorithm

Highest Common Factor of 313,819,860 is 1

Step 1: Since 819 > 313, we apply the division lemma to 819 and 313, to get

819 = 313 x 2 + 193

Step 2: Since the reminder 313 ≠ 0, we apply division lemma to 193 and 313, to get

313 = 193 x 1 + 120

Step 3: We consider the new divisor 193 and the new remainder 120, and apply the division lemma to get

193 = 120 x 1 + 73

We consider the new divisor 120 and the new remainder 73,and apply the division lemma to get

120 = 73 x 1 + 47

We consider the new divisor 73 and the new remainder 47,and apply the division lemma to get

73 = 47 x 1 + 26

We consider the new divisor 47 and the new remainder 26,and apply the division lemma to get

47 = 26 x 1 + 21

We consider the new divisor 26 and the new remainder 21,and apply the division lemma to get

26 = 21 x 1 + 5

We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get

21 = 5 x 4 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 313 and 819 is 1

Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(26,21) = HCF(47,26) = HCF(73,47) = HCF(120,73) = HCF(193,120) = HCF(313,193) = HCF(819,313) .

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

Step 1: Since 860 > 1, we apply the division lemma to 860 and 1, to get

860 = 1 x 860 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 860 is 1

Notice that 1 = HCF(860,1) .
