Given numbers are 445,130,786,731

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

The LCM of 445,130,786,731 is 3323864310.

Find LCM of 445,130,786,731 with Prime Factorization

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

2 x 5 x 89 x 13 x 393 x 731 = 3323864310

Therefore, the lowest common multiple of 445,130,786,731 is 3323864310.

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.

445 x 130 x 786 x 731 = 33238643100

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.

445 : 1, 5, 89, 445

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

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

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,130,786,731, is 1.

Now, the common factors can be found like this.

445:5x 89

130:2x 5x 13

786:2x 3x 131

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 5 = 10

Therefore, the value for common factors is 10.

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 = 33238643100/(1x10)

LCM = 33238643100/10

LCM = 3323864310

Thus, we can understand that the LCM of 445,130,786,731 is 3323864310.
