HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 538, 903, 891 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 538, 903, 891 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 538, 903, 891 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 538, 903, 891 is 1.

HCF(538, 903, 891) = 1

HCF of 538, 903, 891 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 538, 903, 891 is 1.

Highest Common Factor of 538,903,891 using Euclid's algorithm

Highest Common Factor of 538,903,891 is 1

Step 1: Since 903 > 538, we apply the division lemma to 903 and 538, to get

903 = 538 x 1 + 365

Step 2: Since the reminder 538 ≠ 0, we apply division lemma to 365 and 538, to get

538 = 365 x 1 + 173

Step 3: We consider the new divisor 365 and the new remainder 173, and apply the division lemma to get

365 = 173 x 2 + 19

We consider the new divisor 173 and the new remainder 19,and apply the division lemma to get

173 = 19 x 9 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 538 and 903 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(173,19) = HCF(365,173) = HCF(538,365) = HCF(903,538) .

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

Step 1: Since 891 > 1, we apply the division lemma to 891 and 1, to get

891 = 1 x 891 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 891 is 1

Notice that 1 = HCF(891,1) .
