Given numbers are 455,561,805,485

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

The LCM of 455,561,805,485 is 569473905.

Find LCM of 455,561,805,485 with Prime Factorization

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

5 x 7 x 13 x 561 x 23 x 97 = 569473905

Therefore, the lowest common multiple of 455,561,805,485 is 569473905.

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 561 x 805 x 485 = 99657933375

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

561 : 1, 3, 11, 17, 33, 51, 187, 561

805 : 1, 5, 7, 23, 35, 115, 161, 805

485 : 1, 5, 97, 485

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,561,805,485, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

561:3x 11x 17

805:5x 7x 23

485:5x 97

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

5x 5x 7 = 175

Therefore, the value for common factors is 175.

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 = 99657933375/(1x175)

LCM = 99657933375/175

LCM = 569473905

Thus, we can understand that the LCM of 455,561,805,485 is 569473905.
