HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 666, 504, 63, 612 i.e. 9 the largest integer that leaves a remainder zero for all numbers.

HCF of 666, 504, 63, 612 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 666, 504, 63, 612 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 666, 504, 63, 612 is **9**.

HCF(666, 504, 63, 612) = 9

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

Highest common factor (HCF) of 666, 504, 63, 612 is **9**.

**Step 1:** Since 666 > 504, we apply the division lemma to 666 and 504, to get

666 = 504 x 1 + 162

**Step 2:** Since the reminder 504 ≠ 0, we apply division lemma to 162 and 504, to get

504 = 162 x 3 + 18

**Step 3:** We consider the new divisor 162 and the new remainder 18, and apply the division lemma to get

162 = 18 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 666 and 504 is 18

Notice that 18 = HCF(162,18) = HCF(504,162) = HCF(666,504) .

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

**Step 1:** Since 63 > 18, we apply the division lemma to 63 and 18, to get

63 = 18 x 3 + 9

**Step 2:** Since the reminder 18 ≠ 0, we apply division lemma to 9 and 18, 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 18 and 63 is 9

Notice that 9 = HCF(18,9) = HCF(63,18) .

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

**Step 1:** Since 612 > 9, we apply the division lemma to 612 and 9, to get

612 = 9 x 68 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 9 and 612 is 9

Notice that 9 = HCF(612,9) .

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