HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 174, 838, 903 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 174, 838, 903 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 174, 838, 903 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 174, 838, 903 is 1.

HCF(174, 838, 903) = 1

Highest common factor (HCF) of 174, 838, 903 is 1.

Highest Common Factor of 174,838,903 using Euclid's algorithm

Highest Common Factor of 174,838,903 is 1

Step 1: Since 838 > 174, we apply the division lemma to 838 and 174, to get

838 = 174 x 4 + 142

Step 2: Since the reminder 174 ≠ 0, we apply division lemma to 142 and 174, to get

174 = 142 x 1 + 32

Step 3: We consider the new divisor 142 and the new remainder 32, and apply the division lemma to get

142 = 32 x 4 + 14

We consider the new divisor 32 and the new remainder 14,and apply the division lemma to get

32 = 14 x 2 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 174 and 838 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(142,32) = HCF(174,142) = HCF(838,174) .

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

Step 1: Since 903 > 2, we apply the division lemma to 903 and 2, to get

903 = 2 x 451 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 903 is 1

Notice that 1 = HCF(2,1) = HCF(903,2) .
