HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 27, 147, 446 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 27, 147, 446 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 27, 147, 446 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 27, 147, 446 is **1**.

HCF(27, 147, 446) = 1

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

Highest common factor (HCF) of 27, 147, 446 is **1**.

**Step 1:** Since 147 > 27, we apply the division lemma to 147 and 27, to get

147 = 27 x 5 + 12

**Step 2:** Since the reminder 27 ≠ 0, we apply division lemma to 12 and 27, to get

27 = 12 x 2 + 3

**Step 3:** We consider the new divisor 12 and the new remainder 3, and apply the division lemma to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 27 and 147 is 3

Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(147,27) .

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

**Step 1:** Since 446 > 3, we apply the division lemma to 446 and 3, to get

446 = 3 x 148 + 2

**Step 2:** Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

**Step 3:** 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 3 and 446 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(446,3) .

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