Given numbers are 142,450,449,905

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

The LCM of 142,450,449,905 is 2596544550.

Find LCM of 142,450,449,905 with Prime Factorization

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

2 x 5 x 71 x 45 x 449 x 181 = 2596544550

Therefore, the lowest common multiple of 142,450,449,905 is 2596544550.

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.

142 x 450 x 449 x 905 = 25965445500

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.

142 : 1, 2, 71, 142

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

449 : 1, 449

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,450,449,905, is 1.

Now, the common factors can be found like this.

142:2x 71

450:2x 3x 3x 5x 5

449:449

905:5x 181

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 25965445500/(1x10)

LCM = 25965445500/10

LCM = 2596544550

Thus, we can understand that the LCM of 142,450,449,905 is 2596544550.
