Given numbers are 409,880,781,990

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

The LCM of 409,880,781,990 is 229988880.

Find LCM of 409,880,781,990 with Prime Factorization

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

2 x 5 x 11 x 409 x 8 x 71 x 9 = 229988880

Therefore, the lowest common multiple of 409,880,781,990 is 229988880.

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.

409 x 880 x 781 x 990 = 278286544800

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.

409 : 1, 409

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

781 : 1, 11, 71, 781

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,880,781,990, is 1.

Now, the common factors can be found like this.

409:409

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

781:11x 71

990:2x 3x 3x 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.

2x 5x 11x 11 = 1210

Therefore, the value for common factors is 1210.

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 = 278286544800/(1x1210)

LCM = 278286544800/1210

LCM = 229988880

Thus, we can understand that the LCM of 409,880,781,990 is 229988880.
