Given numbers are 128,240,388,615,832

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

The LCM of 128,240,388,615,832 is 99265920.

Find LCM of 128,240,388,615,832 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 5 x 2 x 1 x 97 x 41 x 13 = 99265920

Therefore, the lowest common multiple of 128,240,388,615,832 is 99265920.

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 240 x 388 x 615 x 832 = 6098898124800

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

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

388 : 1, 2, 4, 97, 194, 388

615 : 1, 3, 5, 15, 41, 123, 205, 615

832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,240,388,615,832, is 1.

Now, the common factors can be found like this.

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

240:2x 2x 2x 2x 3x 5

388:2x 2x 97

615:3x 5x 41

832:2x 2x 2x 2x 2x 2x 13

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 2x 2x 2x 3x 5 = 61440

Therefore, the value for common factors is 61440.

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 = 6098898124800/(1x61440)

LCM = 6098898124800/61440

LCM = 99265920

Thus, we can understand that the LCM of 128,240,388,615,832 is 99265920.
