Given numbers are 398,417,880

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

The LCM of 398,417,880 is 73025040.

Find LCM of 398,417,880 with Prime Factorization

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

2 x 199 x 417 x 440 = 73025040

Therefore, the lowest common multiple of 398,417,880 is 73025040.

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 417 x 880 = 146050080

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

417 : 1, 3, 139, 417

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,417,880, is 1.

Now, the common factors can be found like this.

398:2x 199

417:3x 139

880:2x 2x 2x 2x 5x 11

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 = 146050080/(1x2)

LCM = 146050080/2

LCM = 73025040

Thus, we can understand that the LCM of 398,417,880 is 73025040.
