Given numbers are 642,778,753,309,879

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

The LCM of 642,778,753,309,879 is 1891747618602.

Find LCM of 642,778,753,309,879 with Prime Factorization

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

2 x 3 x 107 x 389 x 251 x 103 x 293 = 1891747618602

Therefore, the lowest common multiple of 642,778,753,309,879 is 1891747618602.

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 778 x 753 x 309 x 879 = 102154371404508

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

778 : 1, 2, 389, 778

753 : 1, 3, 251, 753

309 : 1, 3, 103, 309

879 : 1, 3, 293, 879

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,778,753,309,879, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

778:2x 389

753:3x 251

309:3x 103

879:3x 293

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

2x 3x 3x 3 = 54

Therefore, the value for common factors is 54.

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 = 102154371404508/(1x54)

LCM = 102154371404508/54

LCM = 1891747618602

Thus, we can understand that the LCM of 642,778,753,309,879 is 1891747618602.
