Given numbers are 382,455,731,80

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

The LCM of 382,455,731,80 is 1016440880.

Find LCM of 382,455,731,80 with Prime Factorization

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

2 x 5 x 191 x 91 x 731 x 8 = 1016440880

Therefore, the lowest common multiple of 382,455,731,80 is 1016440880.

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.

382 x 455 x 731 x 80 = 10164408800

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.

382 : 1, 2, 191, 382

455 : 1, 5, 7, 13, 35, 65, 91, 455

731 : 1, 17, 43, 731

80 : 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,455,731,80, is 1.

Now, the common factors can be found like this.

382:2x 191

455:5x 7x 13

731:17x 43

80:2x 2x 2x 2x 5

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 = 10164408800/(1x10)

LCM = 10164408800/10

LCM = 1016440880

Thus, we can understand that the LCM of 382,455,731,80 is 1016440880.
