Given numbers are 781,213,388,808

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

The LCM of 781,213,388,808 is 183634968.

Find LCM of 781,213,388,808 with Prime Factorization

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

2 x 2 x 71 x 11 x 3 x 97 x 202 = 183634968

Therefore, the lowest common multiple of 781,213,388,808 is 183634968.

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.

781 x 213 x 388 x 808 = 52152330912

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.

781 : 1, 11, 71, 781

213 : 1, 3, 71, 213

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

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,213,388,808, is 1.

Now, the common factors can be found like this.

781:11x 71

213:3x 71

388:2x 2x 97

808:2x 2x 2x 101

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

2x 2x 71 = 284

Therefore, the value for common factors is 284.

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 = 52152330912/(1x284)

LCM = 52152330912/284

LCM = 183634968

Thus, we can understand that the LCM of 781,213,388,808 is 183634968.
