Given numbers are 398,234,509,919

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

The LCM of 398,234,509,919 is 21782224386.

Find LCM of 398,234,509,919 with Prime Factorization

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

2 x 199 x 117 x 509 x 919 = 21782224386

Therefore, the lowest common multiple of 398,234,509,919 is 21782224386.

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 234 x 509 x 919 = 43564448772

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

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

509 : 1, 509

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,234,509,919, is 1.

Now, the common factors can be found like this.

398:2x 199

234:2x 3x 3x 13

509:509

919:919

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

2 = 2

Therefore, the value for common factors is 2.

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 = 43564448772/(1x2)

LCM = 43564448772/2

LCM = 21782224386

Thus, we can understand that the LCM of 398,234,509,919 is 21782224386.
