Given numbers are 398,368,398,730

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

The LCM of 398,368,398,730 is 26729680.

Find LCM of 398,368,398,730 with Prime Factorization

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

2 x 199 x 1 x 184 x 1 x 365 = 26729680

Therefore, the lowest common multiple of 398,368,398,730 is 26729680.

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 368 x 398 x 730 = 42553650560

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

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

398 : 1, 2, 199, 398

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,368,398,730, is 2.

Now, the common factors can be found like this.

398:2x 199

368:2x 2x 2x 2x 23

398:2x 199

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 199 = 796

Therefore, the value for common factors is 796.

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 = 42553650560/(2x796)

LCM = 42553650560/1592

LCM = 26729680

Thus, we can understand that the LCM of 398,368,398,730 is 26729680.
