Given numbers are 388,485,290,143

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

The LCM of 388,485,290,143 is 8045180.

Find LCM of 388,485,290,143 with Prime Factorization

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

2 x 5 x 97 x 2 x 1 x 29 x 143 = 8045180

Therefore, the lowest common multiple of 388,485,290,143 is 8045180.

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.

388 x 485 x 290 x 143 = 7803824600

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.

388 : 1, 2, 4, 97, 194, 388

485 : 1, 5, 97, 485

290 : 1, 2, 5, 10, 29, 58, 145, 290

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,485,290,143, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

485:5x 97

290:2x 5x 29

143:11x 13

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 97 = 970

Therefore, the value for common factors is 970.

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 = 7803824600/(1x970)

LCM = 7803824600/970

LCM = 8045180

Thus, we can understand that the LCM of 388,485,290,143 is 8045180.
