Given numbers are 390,183,768,364,448

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

The LCM of 390,183,768,364,448 is 21315840.

Find LCM of 390,183,768,364,448 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 3 x 7 x 13 x 5 x 61 x 4 x 1 x 1 = 21315840

Therefore, the lowest common multiple of 390,183,768,364,448 is 21315840.

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.

390 x 183 x 768 x 364 x 448 = 8938328555520

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

183 : 1, 3, 61, 183

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,183,768,364,448, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

183:3x 61

768:2x 2x 2x 2x 2x 2x 2x 2x 3

364:2x 2x 7x 13

448:2x 2x 2x 2x 2x 2x 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 2x 2x 2x 2x 2x 3x 3x 7x 13 = 419328

Therefore, the value for common factors is 419328.

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 = 8938328555520/(1x419328)

LCM = 8938328555520/419328

LCM = 21315840

Thus, we can understand that the LCM of 390,183,768,364,448 is 21315840.
