# Highest Common Factor of 54, 90, 108 using Euclid's algorithm

HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 54, 90, 108 i.e. 18 the largest integer that leaves a remainder zero for all numbers.

HCF of 54, 90, 108 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 54, 90, 108 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 54, 90, 108 is 18.

HCF(54, 90, 108) = 18

## HCF of 54, 90, 108 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 54, 90, 108 is 18.

### Highest Common Factor of 54,90,108 using Euclid's algorithm

Step 1: Since 90 > 54, we apply the division lemma to 90 and 54, to get

90 = 54 x 1 + 36

Step 2: Since the reminder 54 ≠ 0, we apply division lemma to 36 and 54, to get

54 = 36 x 1 + 18

Step 3: We consider the new divisor 36 and the new remainder 18, and apply the division lemma 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 54 and 90 is 18

Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(90,54) .

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

Step 1: Since 108 > 18, we apply the division lemma to 108 and 18, to get

108 = 18 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 18 and 108 is 18

Notice that 18 = HCF(108,18) .
