Given numbers are 487,391,322,646,556

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

The LCM of 487,391,322,646,556 is 14080956316.

Find LCM of 487,391,322,646,556 with Prime Factorization

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

2 x 17 x 23 x 487 x 1 x 7 x 19 x 278 = 14080956316

Therefore, the lowest common multiple of 487,391,322,646,556 is 14080956316.

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.

487 x 391 x 322 x 646 x 556 = 22022615678224

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.

487 : 1, 487

391 : 1, 17, 23, 391

322 : 1, 2, 7, 14, 23, 46, 161, 322

646 : 1, 2, 17, 19, 34, 38, 323, 646

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,391,322,646,556, is 1.

Now, the common factors can be found like this.

487:487

391:17x 23

322:2x 7x 23

646:2x 17x 19

556:2x 2x 139

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 17x 23 = 1564

Therefore, the value for common factors is 1564.

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 = 22022615678224/(1x1564)

LCM = 22022615678224/1564

LCM = 14080956316

Thus, we can understand that the LCM of 487,391,322,646,556 is 14080956316.
