Given numbers are 128,810,782,174,910

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

The LCM of 128,810,782,174,910 is 53491052160.

Find LCM of 128,810,782,174,910 with Prime Factorization

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

2 x 3 x 5 x 64 x 27 x 391 x 29 x 91 = 53491052160

Therefore, the lowest common multiple of 128,810,782,174,910 is 53491052160.

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.

128 x 810 x 782 x 174 x 910 = 12837852518400

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.

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

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

782 : 1, 2, 17, 23, 34, 46, 391, 782

174 : 1, 2, 3, 6, 29, 58, 87, 174

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,810,782,174,910, is 2.

Now, the common factors can be found like this.

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

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

782:2x 17x 23

174:2x 3x 29

910:2x 5x 7x 13

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 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 12837852518400/(2x120)

LCM = 12837852518400/240

LCM = 53491052160

Thus, we can understand that the LCM of 128,810,782,174,910 is 53491052160.
