Given numbers are 720,873,863,487,399

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

The LCM of 720,873,863,487,399 is 3903872530320.

Find LCM of 720,873,863,487,399 with Prime Factorization

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

3 x 3 x 80 x 97 x 863 x 487 x 133 = 3903872530320

Therefore, the lowest common multiple of 720,873,863,487,399 is 3903872530320.

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.

720 x 873 x 863 x 487 x 399 = 105404558318640

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

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

863 : 1, 863

487 : 1, 487

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,873,863,487,399, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

873:3x 3x 97

863:863

487:487

399:3x 7x 19

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 105404558318640/(1x27)

LCM = 105404558318640/27

LCM = 3903872530320

Thus, we can understand that the LCM of 720,873,863,487,399 is 3903872530320.
