Given numbers are 830,878,750,720

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

The LCM of 830,878,750,720 is 655866000.

Find LCM of 830,878,750,720 with Prime Factorization

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

2 x 3 x 5 x 83 x 439 x 25 x 24 = 655866000

Therefore, the lowest common multiple of 830,878,750,720 is 655866000.

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.

830 x 878 x 750 x 720 = 393519600000

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.

830 : 1, 2, 5, 10, 83, 166, 415, 830

878 : 1, 2, 439, 878

750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,878,750,720, is 2.

Now, the common factors can be found like this.

830:2x 5x 83

878:2x 439

750:2x 3x 5x 5x 5

720:2x 2x 2x 2x 3x 3x 5

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 3x 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 393519600000/(2x300)

LCM = 393519600000/600

LCM = 655866000

Thus, we can understand that the LCM of 830,878,750,720 is 655866000.
