Given numbers are 520,390,957,490,486

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

The LCM of 520,390,957,490,486 is 1975133160.

Find LCM of 520,390,957,490,486 with Prime Factorization

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

2 x 3 x 5 x 13 x 4 x 1 x 319 x 49 x 81 = 1975133160

Therefore, the lowest common multiple of 520,390,957,490,486 is 1975133160.

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.

520 x 390 x 957 x 490 x 486 = 46218115944000

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

957 : 1, 3, 11, 29, 33, 87, 319, 957

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,390,957,490,486, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

390:2x 3x 5x 13

957:3x 11x 29

490:2x 5x 7x 7

486:2x 3x 3x 3x 3x 3

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 3x 3x 5x 5x 13 = 23400

Therefore, the value for common factors is 23400.

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 = 46218115944000/(1x23400)

LCM = 46218115944000/23400

LCM = 1975133160

Thus, we can understand that the LCM of 520,390,957,490,486 is 1975133160.
