Given numbers are 778,878,787,878

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

The LCM of 778,878,787,878 is 268793554.

Find LCM of 778,878,787,878 with Prime Factorization

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

2 x 439 x 389 x 1 x 787 x 1 = 268793554

Therefore, the lowest common multiple of 778,878,787,878 is 268793554.

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 878 x 787 x 878 = 472001480824

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

878 : 1, 2, 439, 878

787 : 1, 787

878 : 1, 2, 439, 878

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,878,787,878, is 1.

Now, the common factors can be found like this.

778:2x 389

878:2x 439

787:787

878:2x 439

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 439 = 1756

Therefore, the value for common factors is 1756.

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 = 472001480824/(1x1756)

LCM = 472001480824/1756

LCM = 268793554

Thus, we can understand that the LCM of 778,878,787,878 is 268793554.
