Given numbers are 810,320,726,489

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

The LCM of 810,320,726,489 is 511220160.

Find LCM of 810,320,726,489 with Prime Factorization

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

2 x 3 x 5 x 27 x 32 x 121 x 163 = 511220160

Therefore, the lowest common multiple of 810,320,726,489 is 511220160.

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.

810 x 320 x 726 x 489 = 92019628800

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.

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,320,726,489, is 1.

Now, the common factors can be found like this.

810:2x 3x 3x 3x 3x 5

320:2x 2x 2x 2x 2x 2x 5

726:2x 3x 11x 11

489:3x 163

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 92019628800/(1x180)

LCM = 92019628800/180

LCM = 511220160

Thus, we can understand that the LCM of 810,320,726,489 is 511220160.
