HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 803, 5540, 1144 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 803, 5540, 1144 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 803, 5540, 1144 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 803, 5540, 1144 is 1.

HCF(803, 5540, 1144) = 1

HCF of 803, 5540, 1144 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 803, 5540, 1144 is 1.

Highest Common Factor of 803,5540,1144 using Euclid's algorithm

Highest Common Factor of 803,5540,1144 is 1

Step 1: Since 5540 > 803, we apply the division lemma to 5540 and 803, to get

5540 = 803 x 6 + 722

Step 2: Since the reminder 803 ≠ 0, we apply division lemma to 722 and 803, to get

803 = 722 x 1 + 81

Step 3: We consider the new divisor 722 and the new remainder 81, and apply the division lemma to get

722 = 81 x 8 + 74

We consider the new divisor 81 and the new remainder 74,and apply the division lemma to get

81 = 74 x 1 + 7

We consider the new divisor 74 and the new remainder 7,and apply the division lemma to get

74 = 7 x 10 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 803 and 5540 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(74,7) = HCF(81,74) = HCF(722,81) = HCF(803,722) = HCF(5540,803) .

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

Step 1: Since 1144 > 1, we apply the division lemma to 1144 and 1, to get

1144 = 1 x 1144 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1144 is 1

Notice that 1 = HCF(1144,1) .
