Given numbers are 128,583,756,346,778

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

The LCM of 128,583,756,346,778 is 949152580992.

Find LCM of 128,583,756,346,778 with Prime Factorization

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

2 x 2 x 32 x 583 x 189 x 173 x 389 = 949152580992

Therefore, the lowest common multiple of 128,583,756,346,778 is 949152580992.

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 583 x 756 x 346 x 778 = 15186441295872

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

583 : 1, 11, 53, 583

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

346 : 1, 2, 173, 346

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,583,756,346,778, is 1.

Now, the common factors can be found like this.

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

583:11x 53

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

346:2x 173

778:2x 389

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 = 15186441295872/(1x16)

LCM = 15186441295872/16

LCM = 949152580992

Thus, we can understand that the LCM of 128,583,756,346,778 is 949152580992.
