HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 486, 171, 189 i.e. 9 the largest integer that leaves a remainder zero for all numbers.

HCF of 819, 486, 171, 189 is 9 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 819, 486, 171, 189 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 819, 486, 171, 189 is **9**.

HCF(819, 486, 171, 189) = 9

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

Highest common factor (HCF) of 819, 486, 171, 189 is **9**.

**Step 1:** Since 819 > 486, we apply the division lemma to 819 and 486, to get

819 = 486 x 1 + 333

**Step 2:** Since the reminder 486 ≠ 0, we apply division lemma to 333 and 486, to get

486 = 333 x 1 + 153

**Step 3:** We consider the new divisor 333 and the new remainder 153, and apply the division lemma to get

333 = 153 x 2 + 27

We consider the new divisor 153 and the new remainder 27,and apply the division lemma to get

153 = 27 x 5 + 18

We consider the new divisor 27 and the new remainder 18,and apply the division lemma to get

27 = 18 x 1 + 9

We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get

18 = 9 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 819 and 486 is 9

Notice that 9 = HCF(18,9) = HCF(27,18) = HCF(153,27) = HCF(333,153) = HCF(486,333) = HCF(819,486) .

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

**Step 1:** Since 171 > 9, we apply the division lemma to 171 and 9, to get

171 = 9 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 9 and 171 is 9

Notice that 9 = HCF(171,9) .

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

**Step 1:** Since 189 > 9, we apply the division lemma to 189 and 9, to get

189 = 9 x 21 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 9 and 189 is 9

Notice that 9 = HCF(189,9) .

Here are some samples of HCF using Euclid's Algorithm calculations.
