Given numbers are 455,291,742,509

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

The LCM of 455,291,742,509 is 7143779370.

Find LCM of 455,291,742,509 with Prime Factorization

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

7 x 65 x 291 x 106 x 509 = 7143779370

Therefore, the lowest common multiple of 455,291,742,509 is 7143779370.

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.

455 x 291 x 742 x 509 = 50006455590

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

291 : 1, 3, 97, 291

742 : 1, 2, 7, 14, 53, 106, 371, 742

509 : 1, 509

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,291,742,509, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

291:3x 97

742:2x 7x 53

509:509

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

7 = 7

Therefore, the value for common factors is 7.

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 = 50006455590/(1x7)

LCM = 50006455590/7

LCM = 7143779370

Thus, we can understand that the LCM of 455,291,742,509 is 7143779370.
