Given numbers are 138,872,904,436,508

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

The LCM of 138,872,904,436,508 is 863470968.

Find LCM of 138,872,904,436,508 with Prime Factorization

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

2 x 2 x 2 x 109 x 69 x 1 x 113 x 1 x 127 = 863470968

Therefore, the lowest common multiple of 138,872,904,436,508 is 863470968.

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 872 x 904 x 436 x 508 = 24094293891072

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

872 : 1, 2, 4, 8, 109, 218, 436, 872

904 : 1, 2, 4, 8, 113, 226, 452, 904

436 : 1, 2, 4, 109, 218, 436

508 : 1, 2, 4, 127, 254, 508

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,872,904,436,508, is 2.

Now, the common factors can be found like this.

138:2x 3x 23

872:2x 2x 2x 109

904:2x 2x 2x 113

436:2x 2x 109

508:2x 2x 127

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 2x 2x 2x 2x 109 = 13952

Therefore, the value for common factors is 13952.

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 = 24094293891072/(2x13952)

LCM = 24094293891072/27904

LCM = 863470968

Thus, we can understand that the LCM of 138,872,904,436,508 is 863470968.
