Given numbers are 247,628,461,388

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

The LCM of 247,628,461,388 is 6936322172.

Find LCM of 247,628,461,388 with Prime Factorization

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

2 x 2 x 247 x 157 x 461 x 97 = 6936322172

Therefore, the lowest common multiple of 247,628,461,388 is 6936322172.

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.

247 x 628 x 461 x 388 = 27745288688

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.

247 : 1, 13, 19, 247

628 : 1, 2, 4, 157, 314, 628

461 : 1, 461

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,628,461,388, is 1.

Now, the common factors can be found like this.

247:13x 19

628:2x 2x 157

461:461

388:2x 2x 97

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 = 27745288688/(1x4)

LCM = 27745288688/4

LCM = 6936322172

Thus, we can understand that the LCM of 247,628,461,388 is 6936322172.
