Given numbers are 998,987,924,455

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

The LCM of 998,987,924,455 is 1408587180.

Find LCM of 998,987,924,455 with Prime Factorization

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

2 x 3 x 7 x 499 x 47 x 22 x 65 = 1408587180

Therefore, the lowest common multiple of 998,987,924,455 is 1408587180.

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.

998 x 987 x 924 x 455 = 414124630920

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.

998 : 1, 2, 499, 998

987 : 1, 3, 7, 21, 47, 141, 329, 987

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,987,924,455, is 1.

Now, the common factors can be found like this.

998:2x 499

987:3x 7x 47

924:2x 2x 3x 7x 11

455:5x 7x 13

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

2x 3x 7x 7 = 294

Therefore, the value for common factors is 294.

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 = 414124630920/(1x294)

LCM = 414124630920/294

LCM = 1408587180

Thus, we can understand that the LCM of 998,987,924,455 is 1408587180.
