HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 803, 55 i.e. 11 the largest integer that leaves a remainder zero for all numbers.

HCF of 803, 55 is 11 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, 55 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, 55 is 11.

HCF(803, 55) = 11

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

HCF of:

Highest common factor (HCF) of 803, 55 is 11.

Highest Common Factor of 803,55 using Euclid's algorithm

Highest Common Factor of 803,55 is 11

Step 1: Since 803 > 55, we apply the division lemma to 803 and 55, to get

803 = 55 x 14 + 33

Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 33 and 55, to get

55 = 33 x 1 + 22

Step 3: We consider the new divisor 33 and the new remainder 22, and apply the division lemma to get

33 = 22 x 1 + 11

We consider the new divisor 22 and the new remainder 11, and apply the division lemma to get

22 = 11 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 803 and 55 is 11

Notice that 11 = HCF(22,11) = HCF(33,22) = HCF(55,33) = HCF(803,55) .
