Given numbers are 406,566,788,721

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

The LCM of 406,566,788,721 is 4662790636.

Find LCM of 406,566,788,721 with Prime Factorization

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

2 x 7 x 29 x 283 x 394 x 103 = 4662790636

Therefore, the lowest common multiple of 406,566,788,721 is 4662790636.

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.

406 x 566 x 788 x 721 = 130558137808

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

566 : 1, 2, 283, 566

788 : 1, 2, 4, 197, 394, 788

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,566,788,721, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

566:2x 283

788:2x 2x 197

721:7x 103

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 7 = 28

Therefore, the value for common factors is 28.

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 = 130558137808/(1x28)

LCM = 130558137808/28

LCM = 4662790636

Thus, we can understand that the LCM of 406,566,788,721 is 4662790636.
