HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 321, 2540, 5740 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 321, 2540, 5740 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 321, 2540, 5740 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 321, 2540, 5740 is 1.

HCF(321, 2540, 5740) = 1

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

HCF of:

Highest common factor (HCF) of 321, 2540, 5740 is 1.

Highest Common Factor of 321,2540,5740 using Euclid's algorithm

Highest Common Factor of 321,2540,5740 is 1

Step 1: Since 2540 > 321, we apply the division lemma to 2540 and 321, to get

2540 = 321 x 7 + 293

Step 2: Since the reminder 321 ≠ 0, we apply division lemma to 293 and 321, to get

321 = 293 x 1 + 28

Step 3: We consider the new divisor 293 and the new remainder 28, and apply the division lemma to get

293 = 28 x 10 + 13

We consider the new divisor 28 and the new remainder 13,and apply the division lemma to get

28 = 13 x 2 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 321 and 2540 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(28,13) = HCF(293,28) = HCF(321,293) = HCF(2540,321) .

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

Step 1: Since 5740 > 1, we apply the division lemma to 5740 and 1, to get

5740 = 1 x 5740 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 5740 is 1

Notice that 1 = HCF(5740,1) .
