Given numbers are 396,487,776,990

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

The LCM of 396,487,776,990 is 187066440.

Find LCM of 396,487,776,990 with Prime Factorization

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

2 x 2 x 3 x 3 x 11 x 1 x 487 x 194 x 5 = 187066440

Therefore, the lowest common multiple of 396,487,776,990 is 187066440.

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.

396 x 487 x 776 x 990 = 148156620480

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.

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

487 : 1, 487

776 : 1, 2, 4, 8, 97, 194, 388, 776

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,487,776,990, is 1.

Now, the common factors can be found like this.

396:2x 2x 3x 3x 11

487:487

776:2x 2x 2x 97

990:2x 3x 3x 5x 11

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 3x 3x 11 = 792

Therefore, the value for common factors is 792.

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 = 148156620480/(1x792)

LCM = 148156620480/792

LCM = 187066440

Thus, we can understand that the LCM of 396,487,776,990 is 187066440.
