Given numbers are 390,121,498,867

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

The LCM of 390,121,498,867 is 1131946530.

Find LCM of 390,121,498,867 with Prime Factorization

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

2 x 3 x 65 x 121 x 83 x 289 = 1131946530

Therefore, the lowest common multiple of 390,121,498,867 is 1131946530.

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.

390 x 121 x 498 x 867 = 20375037540

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.

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

121 : 1, 11, 121

498 : 1, 2, 3, 6, 83, 166, 249, 498

867 : 1, 3, 17, 51, 289, 867

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,121,498,867, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

121:11x 11

498:2x 3x 83

867:3x 17x 17

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 3 = 18

Therefore, the value for common factors is 18.

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 = 20375037540/(1x18)

LCM = 20375037540/18

LCM = 1131946530

Thus, we can understand that the LCM of 390,121,498,867 is 1131946530.
