Given numbers are 638,990,482,848

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

The LCM of 638,990,482,848 is 2933702640.

Find LCM of 638,990,482,848 with Prime Factorization

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

2 x 11 x 29 x 45 x 241 x 424 = 2933702640

Therefore, the lowest common multiple of 638,990,482,848 is 2933702640.

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.

638 x 990 x 482 x 848 = 258165832320

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

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

482 : 1, 2, 241, 482

848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,990,482,848, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

990:2x 3x 3x 5x 11

482:2x 241

848:2x 2x 2x 2x 53

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 11 = 44

Therefore, the value for common factors is 44.

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 = 258165832320/(2x44)

LCM = 258165832320/88

LCM = 2933702640

Thus, we can understand that the LCM of 638,990,482,848 is 2933702640.
