Given numbers are 398,990,377,730

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

The LCM of 398,990,377,730 is 5421912210.

Find LCM of 398,990,377,730 with Prime Factorization

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

2 x 5 x 199 x 99 x 377 x 73 = 5421912210

Therefore, the lowest common multiple of 398,990,377,730 is 5421912210.

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 990 x 377 x 730 = 108438244200

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

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

377 : 1, 13, 29, 377

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,990,377,730, is 1.

Now, the common factors can be found like this.

398:2x 199

990:2x 3x 3x 5x 11

377:13x 29

730:2x 5x 73

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 5 = 20

Therefore, the value for common factors is 20.

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 = 108438244200/(1x20)

LCM = 108438244200/20

LCM = 5421912210

Thus, we can understand that the LCM of 398,990,377,730 is 5421912210.
