Given numbers are 778,415,389,439

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

The LCM of 778,415,389,439 is 141739930.

Find LCM of 778,415,389,439 with Prime Factorization

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

389 x 2 x 415 x 1 x 439 = 141739930

Therefore, the lowest common multiple of 778,415,389,439 is 141739930.

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 415 x 389 x 439 = 55136832770

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

415 : 1, 5, 83, 415

389 : 1, 389

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,415,389,439, is 1.

Now, the common factors can be found like this.

778:2x 389

415:5x 83

389:389

439:439

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

389 = 389

Therefore, the value for common factors is 389.

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 = 55136832770/(1x389)

LCM = 55136832770/389

LCM = 141739930

Thus, we can understand that the LCM of 778,415,389,439 is 141739930.
