HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 90, 135, 180 i.e. 45 the largest integer that leaves a remainder zero for all numbers.

HCF of 90, 135, 180 is 45 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 90, 135, 180 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 90, 135, 180 is **45**.

HCF(90, 135, 180) = 45

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

Highest common factor (HCF) of 90, 135, 180 is **45**.

**Step 1:** Since 135 > 90, we apply the division lemma to 135 and 90, to get

135 = 90 x 1 + 45

**Step 2:** Since the reminder 90 ≠ 0, we apply division lemma to 45 and 90, to get

90 = 45 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 45, the HCF of 90 and 135 is 45

Notice that 45 = HCF(90,45) = HCF(135,90) .

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

**Step 1:** Since 180 > 45, we apply the division lemma to 180 and 45, to get

180 = 45 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 45, the HCF of 45 and 180 is 45

Notice that 45 = HCF(180,45) .

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