Given numbers are 1581,2613

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 1581,2613 is 1377051.

Find LCM of 1581,2613 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 527 x 871 = 1377051

Therefore, the lowest common multiple of 1581,2613 is 1377051.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

1581 x 2613 = 4131153

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

1581 : 1, 3, 17, 31, 51, 93, 527, 1581

2613 : 1, 3, 13, 39, 67, 201, 871, 2613

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1581,2613, is 3.

Now, the common factors can be found like this.

1581:3x 17x 31

2613:3x 13x 67

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

= 1

Therefore, the value for common factors is 1.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 4131153/(3x1)

LCM = 4131153/3

LCM = 1377051

Thus, we can understand that the LCM of 1581,2613 is 1377051.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 6114, 5113
