Given numbers are 778,794,160,406

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

The LCM of 778,794,160,406 is 5015983840.

Find LCM of 778,794,160,406 with Prime Factorization

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

2 x 389 x 397 x 80 x 203 = 5015983840

Therefore, the lowest common multiple of 778,794,160,406 is 5015983840.

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.

778 x 794 x 160 x 406 = 40127870720

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.

778 : 1, 2, 389, 778

794 : 1, 2, 397, 794

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

406 : 1, 2, 7, 14, 29, 58, 203, 406

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,794,160,406, is 2.

Now, the common factors can be found like this.

778:2x 389

794:2x 397

160:2x 2x 2x 2x 2x 5

406:2x 7x 29

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 = 40127870720/(2x4)

LCM = 40127870720/8

LCM = 5015983840

Thus, we can understand that the LCM of 778,794,160,406 is 5015983840.
