Given numbers are 391,974,282,990,898

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

The LCM of 391,974,282,990,898 is 3978186251490.

Find LCM of 391,974,282,990,898 with Prime Factorization

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

2 x 3 x 391 x 487 x 47 x 165 x 449 = 3978186251490

Therefore, the lowest common multiple of 391,974,282,990,898 is 3978186251490.

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 974 x 282 x 990 x 898 = 95476470035760

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

974 : 1, 2, 487, 974

282 : 1, 2, 3, 6, 47, 94, 141, 282

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

898 : 1, 2, 449, 898

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,974,282,990,898, is 1.

Now, the common factors can be found like this.

391:17x 23

974:2x 487

282:2x 3x 47

990:2x 3x 3x 5x 11

898:2x 449

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 3 = 24

Therefore, the value for common factors is 24.

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 = 95476470035760/(1x24)

LCM = 95476470035760/24

LCM = 3978186251490

Thus, we can understand that the LCM of 391,974,282,990,898 is 3978186251490.
