Given numbers are 990,752,644,406

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

The LCM of 990,752,644,406 is 1737988560.

Find LCM of 990,752,644,406 with Prime Factorization

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

2 x 2 x 7 x 495 x 188 x 23 x 29 = 1737988560

Therefore, the lowest common multiple of 990,752,644,406 is 1737988560.

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.

990 x 752 x 644 x 406 = 194654718720

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.

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

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

406 : 1, 2, 7, 14, 29, 58, 203, 406

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,752,644,406, is 2.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

752:2x 2x 2x 2x 47

644:2x 2x 7x 23

406:2x 7x 29

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 7 = 56

Therefore, the value for common factors is 56.

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 = 194654718720/(2x56)

LCM = 194654718720/112

LCM = 1737988560

Thus, we can understand that the LCM of 990,752,644,406 is 1737988560.
