Given numbers are 128,350,587,470

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

The LCM of 128,350,587,470 is 617993600.

Find LCM of 128,350,587,470 with Prime Factorization

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

2 x 5 x 64 x 35 x 587 x 47 = 617993600

Therefore, the lowest common multiple of 128,350,587,470 is 617993600.

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 350 x 587 x 470 = 12359872000

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

350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350

587 : 1, 587

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,350,587,470, is 1.

Now, the common factors can be found like this.

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

350:2x 5x 5x 7

587:587

470:2x 5x 47

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 5 = 20

Therefore, the value for common factors is 20.

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 = 12359872000/(1x20)

LCM = 12359872000/20

LCM = 617993600

Thus, we can understand that the LCM of 128,350,587,470 is 617993600.
