HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 44, 22, 81 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 44, 22, 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 44, 22, 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 44, 22, 81 is 1.

HCF(44, 22, 81) = 1

## HCF of 44, 22, 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 44, 22, 81 is 1. ### Highest Common Factor of 44,22,81 is 1

Step 1: Since 44 > 22, we apply the division lemma to 44 and 22, to get

44 = 22 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 44 and 22 is 22

Notice that 22 = HCF(44,22) .

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

Step 1: Since 81 > 22, we apply the division lemma to 81 and 22, to get

81 = 22 x 3 + 15

Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 15 and 22, to get

22 = 15 x 1 + 7

Step 3: We consider the new divisor 15 and the new remainder 7, and apply the division lemma to get

15 = 7 x 2 + 1

We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 22 and 81 is 1

Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(22,15) = HCF(81,22) .
