Given numbers are 128,454,828,717

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

The LCM of 128,454,828,717 is 1437487488.

Find LCM of 128,454,828,717 with Prime Factorization

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

2 x 2 x 3 x 32 x 227 x 69 x 239 = 1437487488

Therefore, the lowest common multiple of 128,454,828,717 is 1437487488.

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 454 x 828 x 717 = 34499699712

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

454 : 1, 2, 227, 454

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

717 : 1, 3, 239, 717

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,454,828,717, is 1.

Now, the common factors can be found like this.

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

454:2x 227

828:2x 2x 3x 3x 23

717:3x 239

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 3 = 24

Therefore, the value for common factors is 24.

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 = 34499699712/(1x24)

LCM = 34499699712/24

LCM = 1437487488

Thus, we can understand that the LCM of 128,454,828,717 is 1437487488.
