Given numbers are 128,215,448,730

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

The LCM of 128,215,448,730 is 14062720.

Find LCM of 128,215,448,730 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 5 x 2 x 43 x 7 x 73 = 14062720

Therefore, the lowest common multiple of 128,215,448,730 is 14062720.

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.

128 x 215 x 448 x 730 = 9000140800

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

215 : 1, 5, 43, 215

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

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,215,448,730, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

215:5x 43

448:2x 2x 2x 2x 2x 2x 7

730:2x 5x 73

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 5 = 640

Therefore, the value for common factors is 640.

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 = 9000140800/(1x640)

LCM = 9000140800/640

LCM = 14062720

Thus, we can understand that the LCM of 128,215,448,730 is 14062720.
