Given numbers are 720,730,511,690

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

The LCM of 720,730,511,690 is 8462160.

Find LCM of 720,730,511,690 with Prime Factorization

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

2 x 3 x 5 x 73 x 24 x 1 x 7 x 23 = 8462160

Therefore, the lowest common multiple of 720,730,511,690 is 8462160.

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.

720 x 730 x 511 x 690 = 185321304000

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.

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

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

511 : 1, 7, 73, 511

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,730,511,690, is 1.

Now, the common factors can be found like this.

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

730:2x 5x 73

511:7x 73

690:2x 3x 5x 23

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 5x 73 = 21900

Therefore, the value for common factors is 21900.

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 = 185321304000/(1x21900)

LCM = 185321304000/21900

LCM = 8462160

Thus, we can understand that the LCM of 720,730,511,690 is 8462160.
