Given numbers are 128,366,973,456,813

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

The LCM of 128,366,973,456,813 is 117353701248.

Find LCM of 128,366,973,456,813 with Prime Factorization

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

2 x 2 x 2 x 3 x 16 x 61 x 973 x 19 x 271 = 117353701248

Therefore, the lowest common multiple of 128,366,973,456,813 is 117353701248.

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 366 x 973 x 456 x 813 = 16898932979712

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

366 : 1, 2, 3, 6, 61, 122, 183, 366

973 : 1, 7, 139, 973

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,366,973,456,813, is 1.

Now, the common factors can be found like this.

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

366:2x 3x 61

973:7x 139

456:2x 2x 2x 3x 19

813:3x 271

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 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 16898932979712/(1x144)

LCM = 16898932979712/144

LCM = 117353701248

Thus, we can understand that the LCM of 128,366,973,456,813 is 117353701248.
