Given numbers are 668,447,990,164

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

The LCM of 668,447,990,164 is 2020001940.

Find LCM of 668,447,990,164 with Prime Factorization

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

2 x 2 x 3 x 167 x 149 x 165 x 41 = 2020001940

Therefore, the lowest common multiple of 668,447,990,164 is 2020001940.

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 447 x 990 x 164 = 48480046560

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

447 : 1, 3, 149, 447

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

164 : 1, 2, 4, 41, 82, 164

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,447,990,164, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

447:3x 149

990:2x 3x 3x 5x 11

164:2x 2x 41

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 = 48480046560/(1x24)

LCM = 48480046560/24

LCM = 2020001940

Thus, we can understand that the LCM of 668,447,990,164 is 2020001940.
