Given numbers are 391,319,481,198

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

The LCM of 391,319,481,198 is 1079903682.

Find LCM of 391,319,481,198 with Prime Factorization

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

11 x 391 x 29 x 481 x 18 = 1079903682

Therefore, the lowest common multiple of 391,319,481,198 is 1079903682.

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.

391 x 319 x 481 x 198 = 11878940502

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.

391 : 1, 17, 23, 391

319 : 1, 11, 29, 319

481 : 1, 13, 37, 481

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,319,481,198, is 1.

Now, the common factors can be found like this.

391:17x 23

319:11x 29

481:13x 37

198:2x 3x 3x 11

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

11 = 11

Therefore, the value for common factors is 11.

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 = 11878940502/(1x11)

LCM = 11878940502/11

LCM = 1079903682

Thus, we can understand that the LCM of 391,319,481,198 is 1079903682.
