HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 32, 80, 81 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 32, 80, 81 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 32, 80, 81 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 32, 80, 81 is 1.

HCF(32, 80, 81) = 1

HCF of 32, 80, 81 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 32, 80, 81 is 1.

Highest Common Factor of 32,80,81 using Euclid's algorithm

Highest Common Factor of 32,80,81 is 1

Step 1: Since 80 > 32, we apply the division lemma to 80 and 32, to get

80 = 32 x 2 + 16

Step 2: Since the reminder 32 ≠ 0, we apply division lemma to 16 and 32, to get

32 = 16 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 32 and 80 is 16

Notice that 16 = HCF(32,16) = HCF(80,32) .


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

Step 1: Since 81 > 16, we apply the division lemma to 81 and 16, to get

81 = 16 x 5 + 1

Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 1 and 16, to get

16 = 1 x 16 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 16 and 81 is 1

Notice that 1 = HCF(16,1) = HCF(81,16) .
