Given numbers are 449,355,228,781

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

The LCM of 449,355,228,781 is 399762660.

Find LCM of 449,355,228,781 with Prime Factorization

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

71 x 449 x 5 x 228 x 11 = 399762660

Therefore, the lowest common multiple of 449,355,228,781 is 399762660.

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.

449 x 355 x 228 x 781 = 28383148860

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.

449 : 1, 449

355 : 1, 5, 71, 355

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,355,228,781, is 1.

Now, the common factors can be found like this.

449:449

355:5x 71

228:2x 2x 3x 19

781:11x 71

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

71 = 71

Therefore, the value for common factors is 71.

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 = 28383148860/(1x71)

LCM = 28383148860/71

LCM = 399762660

Thus, we can understand that the LCM of 449,355,228,781 is 399762660.
