Given numbers are 128,756,782,122,481

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

The LCM of 128,756,782,122,481 is 277538631552.

Find LCM of 128,756,782,122,481 with Prime Factorization

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

2 x 2 x 32 x 189 x 391 x 61 x 481 = 277538631552

Therefore, the lowest common multiple of 128,756,782,122,481 is 277538631552.

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 756 x 782 x 122 x 481 = 4440618104832

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

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

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

122 : 1, 2, 61, 122

481 : 1, 13, 37, 481

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,756,782,122,481, is 1.

Now, the common factors can be found like this.

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

756:2x 2x 3x 3x 3x 7

782:2x 17x 23

122:2x 61

481:13x 37

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 2 = 16

Therefore, the value for common factors is 16.

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 = 4440618104832/(1x16)

LCM = 4440618104832/16

LCM = 277538631552

Thus, we can understand that the LCM of 128,756,782,122,481 is 277538631552.
