Given numbers are 668,268,128,344,304

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

The LCM of 668,268,128,344,304 is 1170100864.

Find LCM of 668,268,128,344,304 with Prime Factorization

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

2 x 2 x 2 x 2 x 167 x 67 x 8 x 43 x 19 = 1170100864

Therefore, the lowest common multiple of 668,268,128,344,304 is 1170100864.

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 268 x 128 x 344 x 304 = 2396366569472

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

268 : 1, 2, 4, 67, 134, 268

128 : 1, 2, 4, 8, 16, 32, 64, 128

344 : 1, 2, 4, 8, 43, 86, 172, 344

304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,268,128,344,304, is 4.

Now, the common factors can be found like this.

668:2x 2x 167

268:2x 2x 67

128:2x 2x 2x 2x 2x 2x 2

344:2x 2x 2x 43

304:2x 2x 2x 2x 19

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 2x 2x 2x 2 = 512

Therefore, the value for common factors is 512.

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 = 2396366569472/(4x512)

LCM = 2396366569472/2048

LCM = 1170100864

Thus, we can understand that the LCM of 668,268,128,344,304 is 1170100864.
