HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 251, 431, 913 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 251, 431, 913 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 251, 431, 913 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 251, 431, 913 is 1.

HCF(251, 431, 913) = 1

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

HCF of:

Highest common factor (HCF) of 251, 431, 913 is 1.

Highest Common Factor of 251,431,913 using Euclid's algorithm

Highest Common Factor of 251,431,913 is 1

Step 1: Since 431 > 251, we apply the division lemma to 431 and 251, to get

431 = 251 x 1 + 180

Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 180 and 251, to get

251 = 180 x 1 + 71

Step 3: We consider the new divisor 180 and the new remainder 71, and apply the division lemma to get

180 = 71 x 2 + 38

We consider the new divisor 71 and the new remainder 38,and apply the division lemma to get

71 = 38 x 1 + 33

We consider the new divisor 38 and the new remainder 33,and apply the division lemma to get

38 = 33 x 1 + 5

We consider the new divisor 33 and the new remainder 5,and apply the division lemma to get

33 = 5 x 6 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 251 and 431 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(33,5) = HCF(38,33) = HCF(71,38) = HCF(180,71) = HCF(251,180) = HCF(431,251) .

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

Step 1: Since 913 > 1, we apply the division lemma to 913 and 1, to get

913 = 1 x 913 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 913 is 1

Notice that 1 = HCF(913,1) .
