Given numbers are 505,440,398,515

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

The LCM of 505,440,398,515 is 910886680.

Find LCM of 505,440,398,515 with Prime Factorization

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

2 x 5 x 101 x 44 x 199 x 103 = 910886680

Therefore, the lowest common multiple of 505,440,398,515 is 910886680.

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.

505 x 440 x 398 x 515 = 45544334000

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.

505 : 1, 5, 101, 505

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

398 : 1, 2, 199, 398

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,440,398,515, is 1.

Now, the common factors can be found like this.

505:5x 101

440:2x 2x 2x 5x 11

398:2x 199

515:5x 103

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

2x 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 45544334000/(1x50)

LCM = 45544334000/50

LCM = 910886680

Thus, we can understand that the LCM of 505,440,398,515 is 910886680.
