Highest Common Factor of 36, 90, 135 using Euclid's algorithm

HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 36, 90, 135 i.e. 9 the largest integer that leaves a remainder zero for all numbers.

HCF of 36, 90, 135 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 36, 90, 135 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, 90, 135 is 9.

HCF(36, 90, 135) = 9

HCF of 36, 90, 135 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 36, 90, 135 is 9.

Highest Common Factor of 36,90,135 using Euclid's algorithm

Step 1: Since 90 > 36, we apply the division lemma to 90 and 36, to get

90 = 36 x 2 + 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 90 is 18

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


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

Step 1: Since 135 > 18, we apply the division lemma to 135 and 18, to get

135 = 18 x 7 + 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 135 is 9

Notice that 9 = HCF(18,9) = HCF(135,18) .
