HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 36, 54, 126 i.e. 18 the largest integer that leaves a remainder zero for all numbers.

HCF of 36, 54, 126 is 18 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 36, 54, 126 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 36, 54, 126 is **18**.

HCF(36, 54, 126) = 18

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

Highest common factor (HCF) of 36, 54, 126 is **18**.

**Step 1:** Since 54 > 36, we apply the division lemma to 54 and 36, to get

54 = 36 x 1 + 18

**Step 2:** Since the reminder 36 ≠ 0, we apply division lemma to 18 and 36, to get

36 = 18 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 36 and 54 is 18

Notice that 18 = HCF(36,18) = HCF(54,36) .

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

**Step 1:** Since 126 > 18, we apply the division lemma to 126 and 18, to get

126 = 18 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 18 and 126 is 18

Notice that 18 = HCF(126,18) .

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