Given numbers are 778,485,291,391

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

The LCM of 778,485,291,391 is 442608090.

Find LCM of 778,485,291,391 with Prime Factorization

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

97 x 778 x 5 x 3 x 391 = 442608090

Therefore, the lowest common multiple of 778,485,291,391 is 442608090.

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 485 x 291 x 391 = 42932984730

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

485 : 1, 5, 97, 485

291 : 1, 3, 97, 291

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,485,291,391, is 1.

Now, the common factors can be found like this.

778:2x 389

485:5x 97

291:3x 97

391:17x 23

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

97 = 97

Therefore, the value for common factors is 97.

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 = 42932984730/(1x97)

LCM = 42932984730/97

LCM = 442608090

Thus, we can understand that the LCM of 778,485,291,391 is 442608090.
