Given numbers are 331,614,921,842

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

The LCM of 331,614,921,842 is 256684542.

Find LCM of 331,614,921,842 with Prime Factorization

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

2 x 307 x 331 x 1 x 3 x 421 = 256684542

Therefore, the lowest common multiple of 331,614,921,842 is 256684542.

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 614 x 921 x 842 = 157604308788

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

614 : 1, 2, 307, 614

921 : 1, 3, 307, 921

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,614,921,842, is 1.

Now, the common factors can be found like this.

331:331

614:2x 307

921:3x 307

842:2x 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 307 = 614

Therefore, the value for common factors is 614.

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 = 157604308788/(1x614)

LCM = 157604308788/614

LCM = 256684542

Thus, we can understand that the LCM of 331,614,921,842 is 256684542.
