Given numbers are 991,212,331,560

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

The LCM of 991,212,331,560 is 9735663280.

Find LCM of 991,212,331,560 with Prime Factorization

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

2 x 2 x 991 x 53 x 331 x 140 = 9735663280

Therefore, the lowest common multiple of 991,212,331,560 is 9735663280.

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.

991 x 212 x 331 x 560 = 38942653120

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.

991 : 1, 991

212 : 1, 2, 4, 53, 106, 212

331 : 1, 331

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,212,331,560, is 1.

Now, the common factors can be found like this.

991:991

212:2x 2x 53

331:331

560:2x 2x 2x 2x 5x 7

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 = 38942653120/(1x4)

LCM = 38942653120/4

LCM = 9735663280

Thus, we can understand that the LCM of 991,212,331,560 is 9735663280.
