Given numbers are 908,489,137,578,638

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

The LCM of 908,489,137,578,638 is 5607945710004.

Find LCM of 908,489,137,578,638 with Prime Factorization

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

2 x 454 x 489 x 137 x 289 x 319 = 5607945710004

Therefore, the lowest common multiple of 908,489,137,578,638 is 5607945710004.

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.

908 x 489 x 137 x 578 x 638 = 22431782840016

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.

908 : 1, 2, 4, 227, 454, 908

489 : 1, 3, 163, 489

137 : 1, 137

578 : 1, 2, 17, 34, 289, 578

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 908,489,137,578,638, is 1.

Now, the common factors can be found like this.

908:2x 2x 227

489:3x 163

137:137

578:2x 17x 17

638:2x 11x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 22431782840016/(1x4)

LCM = 22431782840016/4

LCM = 5607945710004

Thus, we can understand that the LCM of 908,489,137,578,638 is 5607945710004.
