Given numbers are 642,864,703,891

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

The LCM of 642,864,703,891 is 2144701152.

Find LCM of 642,864,703,891 with Prime Factorization

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

2 x 3 x 3 x 3 x 107 x 16 x 703 x 33 = 2144701152

Therefore, the lowest common multiple of 642,864,703,891 is 2144701152.

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 864 x 703 x 891 = 347441586624

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

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

703 : 1, 19, 37, 703

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,864,703,891, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

864:2x 2x 2x 2x 2x 3x 3x 3

703:19x 37

891:3x 3x 3x 3x 11

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 3x 3 = 162

Therefore, the value for common factors is 162.

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 = 347441586624/(1x162)

LCM = 347441586624/162

LCM = 2144701152

Thus, we can understand that the LCM of 642,864,703,891 is 2144701152.
