Given numbers are 720,778,614,395

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

The LCM of 720,778,614,395 is 6792780240.

Find LCM of 720,778,614,395 with Prime Factorization

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

2 x 5 x 72 x 389 x 307 x 79 = 6792780240

Therefore, the lowest common multiple of 720,778,614,395 is 6792780240.

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.

720 x 778 x 614 x 395 = 135855604800

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

778 : 1, 2, 389, 778

614 : 1, 2, 307, 614

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,778,614,395, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

778:2x 389

614:2x 307

395:5x 79

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 5 = 20

Therefore, the value for common factors is 20.

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 = 135855604800/(1x20)

LCM = 135855604800/20

LCM = 6792780240

Thus, we can understand that the LCM of 720,778,614,395 is 6792780240.
