Given numbers are 725,406,580,409

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

The LCM of 725,406,580,409 is 8302700.

Find LCM of 725,406,580,409 with Prime Factorization

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

2 x 5 x 29 x 5 x 7 x 2 x 409 = 8302700

Therefore, the lowest common multiple of 725,406,580,409 is 8302700.

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.

725 x 406 x 580 x 409 = 69825707000

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.

725 : 1, 5, 25, 29, 145, 725

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

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,406,580,409, is 1.

Now, the common factors can be found like this.

725:5x 5x 29

406:2x 7x 29

580:2x 2x 5x 29

409:409

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

2x 5x 29x 29 = 8410

Therefore, the value for common factors is 8410.

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 = 69825707000/(1x8410)

LCM = 69825707000/8410

LCM = 8302700

Thus, we can understand that the LCM of 725,406,580,409 is 8302700.
