Given numbers are 130,730,910,720

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

The LCM of 130,730,910,720 is 4782960.

Find LCM of 130,730,910,720 with Prime Factorization

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

2 x 5 x 13 x 1 x 73 x 7 x 72 = 4782960

Therefore, the lowest common multiple of 130,730,910,720 is 4782960.

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.

130 x 730 x 910 x 720 = 62178480000

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.

130 : 1, 2, 5, 10, 13, 26, 65, 130

730 : 1, 2, 5, 10, 73, 146, 365, 730

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

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

10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,730,910,720, is 10.

Now, the common factors can be found like this.

130:2x 5x 13

730:2x 5x 73

910:2x 5x 7x 13

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 5x 5x 13 = 1300

Therefore, the value for common factors is 1300.

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 = 62178480000/(10x1300)

LCM = 62178480000/13000

LCM = 4782960

Thus, we can understand that the LCM of 130,730,910,720 is 4782960.
