Given numbers are 660,544,908,454

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

The LCM of 660,544,908,454 is 20375520.

Find LCM of 660,544,908,454 with Prime Factorization

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

2 x 2 x 227 x 165 x 136 x 1 x 1 = 20375520

Therefore, the lowest common multiple of 660,544,908,454 is 20375520.

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.

660 x 544 x 908 x 454 = 148007777280

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

908 : 1, 2, 4, 227, 454, 908

454 : 1, 2, 227, 454

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,544,908,454, is 2.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

544:2x 2x 2x 2x 2x 17

908:2x 2x 227

454:2x 227

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 227 = 3632

Therefore, the value for common factors is 3632.

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 = 148007777280/(2x3632)

LCM = 148007777280/7264

LCM = 20375520

Thus, we can understand that the LCM of 660,544,908,454 is 20375520.
