Given numbers are 455,104,551,642

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

The LCM of 455,104,551,642 is 643810440.

Find LCM of 455,104,551,642 with Prime Factorization

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

2 x 13 x 35 x 4 x 551 x 321 = 643810440

Therefore, the lowest common multiple of 455,104,551,642 is 643810440.

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 104 x 551 x 642 = 16739071440

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

104 : 1, 2, 4, 8, 13, 26, 52, 104

551 : 1, 19, 29, 551

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,104,551,642, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

104:2x 2x 2x 13

551:19x 29

642:2x 3x 107

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 16739071440/(1x26)

LCM = 16739071440/26

LCM = 643810440

Thus, we can understand that the LCM of 455,104,551,642 is 643810440.
