Given numbers are 398,204,115,782

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

The LCM of 398,204,115,782 is 4668540.

Find LCM of 398,204,115,782 with Prime Factorization

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

2 x 17 x 23 x 199 x 6 x 5 x 1 = 4668540

Therefore, the lowest common multiple of 398,204,115,782 is 4668540.

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.

398 x 204 x 115 x 782 = 7301596560

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.

398 : 1, 2, 199, 398

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

115 : 1, 5, 23, 115

782 : 1, 2, 17, 23, 34, 46, 391, 782

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,204,115,782, is 1.

Now, the common factors can be found like this.

398:2x 199

204:2x 2x 3x 17

115:5x 23

782:2x 17x 23

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 17x 23 = 1564

Therefore, the value for common factors is 1564.

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 = 7301596560/(1x1564)

LCM = 7301596560/1564

LCM = 4668540

Thus, we can understand that the LCM of 398,204,115,782 is 4668540.
