Given numbers are 2,731,561,581

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

The LCM of 2,731,561,581 is 28030926.

Find LCM of 2,731,561,581 with Prime Factorization

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

17 x 2 x 43 x 33 x 581 = 28030926

Therefore, the lowest common multiple of 2,731,561,581 is 28030926.

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.

2 x 731 x 561 x 581 = 476525742

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.

2 : 1, 2

731 : 1, 17, 43, 731

561 : 1, 3, 11, 17, 33, 51, 187, 561

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2,731,561,581, is 1.

Now, the common factors can be found like this.

2:2

731:17x 43

561:3x 11x 17

581:7x 83

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

17 = 17

Therefore, the value for common factors is 17.

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 = 476525742/(1x17)

LCM = 476525742/17

LCM = 28030926

Thus, we can understand that the LCM of 2,731,561,581 is 28030926.
