Given numbers are 660,408,306,873

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

The LCM of 660,408,306,873 is 6530040.

Find LCM of 660,408,306,873 with Prime Factorization

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

2 x 2 x 3 x 3 x 17 x 55 x 2 x 1 x 97 = 6530040

Therefore, the lowest common multiple of 660,408,306,873 is 6530040.

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.

660 x 408 x 306 x 873 = 71934920640

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

873 : 1, 3, 9, 97, 291, 873

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,408,306,873, is 3.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

408:2x 2x 2x 3x 17

306:2x 3x 3x 17

873:3x 3x 97

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

2x 2x 2x 3x 3x 3x 17 = 3672

Therefore, the value for common factors is 3672.

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 = 71934920640/(3x3672)

LCM = 71934920640/11016

LCM = 6530040

Thus, we can understand that the LCM of 660,408,306,873 is 6530040.
