Given numbers are 668,568,248,422,391

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

The LCM of 668,568,248,422,391 is 242597160536.

Find LCM of 668,568,248,422,391 with Prime Factorization

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

2 x 2 x 2 x 167 x 71 x 31 x 211 x 391 = 242597160536

Therefore, the lowest common multiple of 668,568,248,422,391 is 242597160536.

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.

668 x 568 x 248 x 422 x 391 = 15526218274304

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.

668 : 1, 2, 4, 167, 334, 668

568 : 1, 2, 4, 8, 71, 142, 284, 568

248 : 1, 2, 4, 8, 31, 62, 124, 248

422 : 1, 2, 211, 422

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,568,248,422,391, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

568:2x 2x 2x 71

248:2x 2x 2x 31

422:2x 211

391:17x 23

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 2x 2x 2x 2 = 64

Therefore, the value for common factors is 64.

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 = 15526218274304/(1x64)

LCM = 15526218274304/64

LCM = 242597160536

Thus, we can understand that the LCM of 668,568,248,422,391 is 242597160536.
