Given numbers are 138,858,990,282

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

The LCM of 138,858,990,282 is 13912470.

Find LCM of 138,858,990,282 with Prime Factorization

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

2 x 3 x 11 x 23 x 13 x 15 x 47 = 13912470

Therefore, the lowest common multiple of 138,858,990,282 is 13912470.

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.

138 x 858 x 990 x 282 = 33056028720

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

282 : 1, 2, 3, 6, 47, 94, 141, 282

6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,858,990,282, is 6.

Now, the common factors can be found like this.

138:2x 3x 23

858:2x 3x 11x 13

990:2x 3x 3x 5x 11

282:2x 3x 47

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 3x 3x 11 = 396

Therefore, the value for common factors is 396.

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 = 33056028720/(6x396)

LCM = 33056028720/2376

LCM = 13912470

Thus, we can understand that the LCM of 138,858,990,282 is 13912470.
