Given numbers are 428,540,128,479,187

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

The LCM of 428,540,128,479,187 is 165616894080.

Find LCM of 428,540,128,479,187 with Prime Factorization

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

2 x 2 x 107 x 135 x 32 x 479 x 187 = 165616894080

Therefore, the lowest common multiple of 428,540,128,479,187 is 165616894080.

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.

428 x 540 x 128 x 479 x 187 = 2649870305280

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.

428 : 1, 2, 4, 107, 214, 428

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

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

479 : 1, 479

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,540,128,479,187, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

540:2x 2x 3x 3x 3x 5

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

479:479

187:11x 17

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 2 = 16

Therefore, the value for common factors is 16.

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 = 2649870305280/(1x16)

LCM = 2649870305280/16

LCM = 165616894080

Thus, we can understand that the LCM of 428,540,128,479,187 is 165616894080.
