Given numbers are 668,836,880,990

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

The LCM of 668,836,880,990 is 25130160.

Find LCM of 668,836,880,990 with Prime Factorization

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

2 x 2 x 5 x 11 x 167 x 19 x 4 x 9 = 25130160

Therefore, the lowest common multiple of 668,836,880,990 is 25130160.

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.

668 x 836 x 880 x 990 = 486519897600

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.

668 : 1, 2, 4, 167, 334, 668

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,836,880,990, is 2.

Now, the common factors can be found like this.

668:2x 2x 167

836:2x 2x 11x 19

880:2x 2x 2x 2x 5x 11

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 2x 5x 11x 11 = 9680

Therefore, the value for common factors is 9680.

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 = 486519897600/(2x9680)

LCM = 486519897600/19360

LCM = 25130160

Thus, we can understand that the LCM of 668,836,880,990 is 25130160.
