Given numbers are 322,120,398

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

The LCM of 322,120,398 is 3844680.

Find LCM of 322,120,398 with Prime Factorization

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

2 x 161 x 60 x 199 = 3844680

Therefore, the lowest common multiple of 322,120,398 is 3844680.

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.

322 x 120 x 398 = 15378720

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.

322 : 1, 2, 7, 14, 23, 46, 161, 322

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

398 : 1, 2, 199, 398

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,120,398, is 2.

Now, the common factors can be found like this.

322:2x 7x 23

120:2x 2x 2x 3x 5

398:2x 199

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 = 15378720/(2x2)

LCM = 15378720/4

LCM = 3844680

Thus, we can understand that the LCM of 322,120,398 is 3844680.
