Given numbers are 642,818,542,513,884

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

The LCM of 642,818,542,513,884 is 5378312177316.

Find LCM of 642,818,542,513,884 with Prime Factorization

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

2 x 3 x 107 x 409 x 271 x 171 x 442 = 5378312177316

Therefore, the lowest common multiple of 642,818,542,513,884 is 5378312177316.

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.

642 x 818 x 542 x 513 x 884 = 129079492255584

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.

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

818 : 1, 2, 409, 818

542 : 1, 2, 271, 542

513 : 1, 3, 9, 19, 27, 57, 171, 513

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,818,542,513,884, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

818:2x 409

542:2x 271

513:3x 3x 3x 19

884:2x 2x 13x 17

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 129079492255584/(1x24)

LCM = 129079492255584/24

LCM = 5378312177316

Thus, we can understand that the LCM of 642,818,542,513,884 is 5378312177316.
