Given numbers are 778,655,485,280

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

The LCM of 778,655,485,280 is 1384046440.

Find LCM of 778,655,485,280 with Prime Factorization

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

2 x 5 x 389 x 131 x 97 x 28 = 1384046440

Therefore, the lowest common multiple of 778,655,485,280 is 1384046440.

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 655 x 485 x 280 = 69202322000

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

655 : 1, 5, 131, 655

485 : 1, 5, 97, 485

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,655,485,280, is 1.

Now, the common factors can be found like this.

778:2x 389

655:5x 131

485:5x 97

280:2x 2x 2x 5x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 69202322000/(1x50)

LCM = 69202322000/50

LCM = 1384046440

Thus, we can understand that the LCM of 778,655,485,280 is 1384046440.
