HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 231, 920, 251 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 231, 920, 251 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 231, 920, 251 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 231, 920, 251 is 1.

HCF(231, 920, 251) = 1

HCF of 231, 920, 251 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 231, 920, 251 is 1.

Highest Common Factor of 231,920,251 using Euclid's algorithm

Highest Common Factor of 231,920,251 is 1

Step 1: Since 920 > 231, we apply the division lemma to 920 and 231, to get

920 = 231 x 3 + 227

Step 2: Since the reminder 231 ≠ 0, we apply division lemma to 227 and 231, to get

231 = 227 x 1 + 4

Step 3: We consider the new divisor 227 and the new remainder 4, and apply the division lemma to get

227 = 4 x 56 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 231 and 920 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(227,4) = HCF(231,227) = HCF(920,231) .

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

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

251 = 1 x 251 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 251 is 1

Notice that 1 = HCF(251,1) .
