Given numbers are 331,646,149,298,921

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

The LCM of 331,646,149,298,921 is 29343128154.

Find LCM of 331,646,149,298,921 with Prime Factorization

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

2 x 149 x 331 x 323 x 1 x 1 x 921 = 29343128154

Therefore, the lowest common multiple of 331,646,149,298,921 is 29343128154.

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.

331 x 646 x 149 x 298 x 921 = 8744252189892

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.

331 : 1, 331

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

149 : 1, 149

298 : 1, 2, 149, 298

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,646,149,298,921, is 1.

Now, the common factors can be found like this.

331:331

646:2x 17x 19

149:149

298:2x 149

921:3x 307

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

2x 149 = 298

Therefore, the value for common factors is 298.

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 = 8744252189892/(1x298)

LCM = 8744252189892/298

LCM = 29343128154

Thus, we can understand that the LCM of 331,646,149,298,921 is 29343128154.
