Given numbers are 418,988,660,356

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

The LCM of 418,988,660,356 is 14508780.

Find LCM of 418,988,660,356 with Prime Factorization

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

2 x 2 x 11 x 19 x 1 x 13 x 15 x 89 = 14508780

Therefore, the lowest common multiple of 418,988,660,356 is 14508780.

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.

418 x 988 x 660 x 356 = 97034720640

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

356 : 1, 2, 4, 89, 178, 356

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,988,660,356, is 2.

Now, the common factors can be found like this.

418:2x 11x 19

988:2x 2x 13x 19

660:2x 2x 3x 5x 11

356:2x 2x 89

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

2x 2x 2x 2x 11x 19 = 3344

Therefore, the value for common factors is 3344.

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 = 97034720640/(2x3344)

LCM = 97034720640/6688

LCM = 14508780

Thus, we can understand that the LCM of 418,988,660,356 is 14508780.
