Given numbers are 803,660,621,849,440

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

The LCM of 803,660,621,849,440 is 5644865160.

Find LCM of 803,660,621,849,440 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 73 x 1 x 207 x 283 x 2 = 5644865160

Therefore, the lowest common multiple of 803,660,621,849,440 is 5644865160.

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.

803 x 660 x 621 x 849 x 440 = 122945163184800

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.

803 : 1, 11, 73, 803

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

621 : 1, 3, 9, 23, 27, 69, 207, 621

849 : 1, 3, 283, 849

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,660,621,849,440, is 1.

Now, the common factors can be found like this.

803:11x 73

660:2x 2x 3x 5x 11

621:3x 3x 3x 23

849:3x 283

440:2x 2x 2x 5x 11

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 5x 11x 11 = 21780

Therefore, the value for common factors is 21780.

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 = 122945163184800/(1x21780)

LCM = 122945163184800/21780

LCM = 5644865160

Thus, we can understand that the LCM of 803,660,621,849,440 is 5644865160.
