Given numbers are 555,468,996,420

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

The LCM of 555,468,996,420 is 50302980.

Find LCM of 555,468,996,420 with Prime Factorization

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

2 x 2 x 3 x 5 x 37 x 39 x 83 x 7 = 50302980

Therefore, the lowest common multiple of 555,468,996,420 is 50302980.

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.

555 x 468 x 996 x 420 = 108654436800

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.

555 : 1, 3, 5, 15, 37, 111, 185, 555

468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,468,996,420, is 3.

Now, the common factors can be found like this.

555:3x 5x 37

468:2x 2x 3x 3x 13

996:2x 2x 3x 83

420:2x 2x 3x 5x 7

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 2x 3x 3x 5 = 720

Therefore, the value for common factors is 720.

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 = 108654436800/(3x720)

LCM = 108654436800/2160

LCM = 50302980

Thus, we can understand that the LCM of 555,468,996,420 is 50302980.
