Given numbers are 138,897,460,489

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

The LCM of 138,897,460,489 is 2924220.

Find LCM of 138,897,460,489 with Prime Factorization

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

2 x 3 x 23 x 1 x 13 x 10 x 163 = 2924220

Therefore, the lowest common multiple of 138,897,460,489 is 2924220.

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 897 x 460 x 489 = 27844422840

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

897 : 1, 3, 13, 23, 39, 69, 299, 897

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,897,460,489, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

897:3x 13x 23

460:2x 2x 5x 23

489:3x 163

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 23x 23 = 9522

Therefore, the value for common factors is 9522.

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 = 27844422840/(1x9522)

LCM = 27844422840/9522

LCM = 2924220

Thus, we can understand that the LCM of 138,897,460,489 is 2924220.
