Given numbers are 631,530,286,778

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

The LCM of 631,530,286,778 is 18603337610.

Find LCM of 631,530,286,778 with Prime Factorization

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

2 x 631 x 265 x 143 x 389 = 18603337610

Therefore, the lowest common multiple of 631,530,286,778 is 18603337610.

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.

631 x 530 x 286 x 778 = 74413350440

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.

631 : 1, 631

530 : 1, 2, 5, 10, 53, 106, 265, 530

286 : 1, 2, 11, 13, 22, 26, 143, 286

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,530,286,778, is 1.

Now, the common factors can be found like this.

631:631

530:2x 5x 53

286:2x 11x 13

778:2x 389

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 74413350440/(1x4)

LCM = 74413350440/4

LCM = 18603337610

Thus, we can understand that the LCM of 631,530,286,778 is 18603337610.
