HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 401, 251, 103 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 401, 251, 103 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 401, 251, 103 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 401, 251, 103 is 1.

HCF(401, 251, 103) = 1

Highest Common Factor of 401,251,103 using Euclid's algorithm

Highest Common Factor of 401,251,103 is 1

Step 1: Since 401 > 251, we apply the division lemma to 401 and 251, to get

401 = 251 x 1 + 150

Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 150 and 251, to get

251 = 150 x 1 + 101

Step 3: We consider the new divisor 150 and the new remainder 101, and apply the division lemma to get

150 = 101 x 1 + 49

We consider the new divisor 101 and the new remainder 49,and apply the division lemma to get

101 = 49 x 2 + 3

We consider the new divisor 49 and the new remainder 3,and apply the division lemma to get

49 = 3 x 16 + 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 401 and 251 is 1

Notice that 1 = HCF(3,1) = HCF(49,3) = HCF(101,49) = HCF(150,101) = HCF(251,150) = HCF(401,251) .

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

Step 1: Since 103 > 1, we apply the division lemma to 103 and 1, to get

103 = 1 x 103 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 103 is 1

Notice that 1 = HCF(103,1) .
