Given numbers are 665,810,873,128,480

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

The LCM of 665,810,873,128,480 is 668787840.

Find LCM of 665,810,873,128,480 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 3 x 3 x 5 x 133 x 9 x 97 x 4 x 1 = 668787840

Therefore, the lowest common multiple of 665,810,873,128,480 is 668787840.

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.

665 x 810 x 873 x 128 x 480 = 28891634688000

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

873 : 1, 3, 9, 97, 291, 873

128 : 1, 2, 4, 8, 16, 32, 64, 128

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,810,873,128,480, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

810:2x 3x 3x 3x 3x 5

873:3x 3x 97

128:2x 2x 2x 2x 2x 2x 2

480:2x 2x 2x 2x 2x 3x 5

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 2x 2x 3x 3x 3x 5x 5 = 43200

Therefore, the value for common factors is 43200.

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 = 28891634688000/(1x43200)

LCM = 28891634688000/43200

LCM = 668787840

Thus, we can understand that the LCM of 665,810,873,128,480 is 668787840.
