Given numbers are 130,550,731,643

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

The LCM of 130,550,731,643 is 3360735950.

Find LCM of 130,550,731,643 with Prime Factorization

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

2 x 5 x 13 x 55 x 731 x 643 = 3360735950

Therefore, the lowest common multiple of 130,550,731,643 is 3360735950.

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 550 x 731 x 643 = 33607359500

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

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

731 : 1, 17, 43, 731

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,550,731,643, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

550:2x 5x 5x 11

731:17x 43

643:643

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 = 33607359500/(1x10)

LCM = 33607359500/10

LCM = 3360735950

Thus, we can understand that the LCM of 130,550,731,643 is 3360735950.
