Given numbers are 261,778,481,15

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

The LCM of 261,778,481,15 is 488354490.

Find LCM of 261,778,481,15 with Prime Factorization

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

3 x 87 x 778 x 481 x 5 = 488354490

Therefore, the lowest common multiple of 261,778,481,15 is 488354490.

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.

261 x 778 x 481 x 15 = 1465063470

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.

261 : 1, 3, 9, 29, 87, 261

778 : 1, 2, 389, 778

481 : 1, 13, 37, 481

15 : 1, 3, 5, 15

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,778,481,15, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

778:2x 389

481:13x 37

15:3x 5

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

3 = 3

Therefore, the value for common factors is 3.

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 = 1465063470/(1x3)

LCM = 1465063470/3

LCM = 488354490

Thus, we can understand that the LCM of 261,778,481,15 is 488354490.
