Given numbers are 646,346,985,404

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

The LCM of 646,346,985,404 is 22236489260.

Find LCM of 646,346,985,404 with Prime Factorization

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

2 x 323 x 173 x 985 x 202 = 22236489260

Therefore, the lowest common multiple of 646,346,985,404 is 22236489260.

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.

646 x 346 x 985 x 404 = 88945957040

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

346 : 1, 2, 173, 346

985 : 1, 5, 197, 985

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,346,985,404, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

346:2x 173

985:5x 197

404:2x 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 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 = 88945957040/(1x4)

LCM = 88945957040/4

LCM = 22236489260

Thus, we can understand that the LCM of 646,346,985,404 is 22236489260.
