Given numbers are 668,298,878,421

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

The LCM of 668,298,878,421 is 18395404708.

Find LCM of 668,298,878,421 with Prime Factorization

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

2 x 334 x 149 x 439 x 421 = 18395404708

Therefore, the lowest common multiple of 668,298,878,421 is 18395404708.

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.

668 x 298 x 878 x 421 = 73581618832

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.

668 : 1, 2, 4, 167, 334, 668

298 : 1, 2, 149, 298

878 : 1, 2, 439, 878

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,298,878,421, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

298:2x 149

878:2x 439

421:421

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 73581618832/(1x4)

LCM = 73581618832/4

LCM = 18395404708

Thus, we can understand that the LCM of 668,298,878,421 is 18395404708.
