Given numbers are 746,128,691,778

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

The LCM of 746,128,691,778 is 12833539456.

Find LCM of 746,128,691,778 with Prime Factorization

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

2 x 373 x 64 x 691 x 389 = 12833539456

Therefore, the lowest common multiple of 746,128,691,778 is 12833539456.

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.

746 x 128 x 691 x 778 = 51334157824

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.

746 : 1, 2, 373, 746

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

691 : 1, 691

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,128,691,778, is 1.

Now, the common factors can be found like this.

746:2x 373

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

691:691

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 2 = 4

Therefore, the value for common factors is 4.

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 = 51334157824/(1x4)

LCM = 51334157824/4

LCM = 12833539456

Thus, we can understand that the LCM of 746,128,691,778 is 12833539456.
