Given numbers are 720,786,513,731

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

The LCM of 720,786,513,731 is 3930031440.

Find LCM of 720,786,513,731 with Prime Factorization

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

2 x 3 x 3 x 40 x 131 x 57 x 731 = 3930031440

Therefore, the lowest common multiple of 720,786,513,731 is 3930031440.

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 786 x 513 x 731 = 212221697760

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

786 : 1, 2, 3, 6, 131, 262, 393, 786

513 : 1, 3, 9, 19, 27, 57, 171, 513

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,786,513,731, is 1.

Now, the common factors can be found like this.

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

786:2x 3x 131

513:3x 3x 3x 19

731:17x 43

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3x 3 = 54

Therefore, the value for common factors is 54.

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 = 212221697760/(1x54)

LCM = 212221697760/54

LCM = 3930031440

Thus, we can understand that the LCM of 720,786,513,731 is 3930031440.
