Given numbers are 668,684,289,248

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

The LCM of 668,684,289,248 is 2046737304.

Find LCM of 668,684,289,248 with Prime Factorization

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

2 x 2 x 167 x 171 x 289 x 62 = 2046737304

Therefore, the lowest common multiple of 668,684,289,248 is 2046737304.

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 684 x 289 x 248 = 32747796864

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

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

289 : 1, 17, 289

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,684,289,248, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

684:2x 2x 3x 3x 19

289:17x 17

248:2x 2x 2x 31

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 2 = 16

Therefore, the value for common factors is 16.

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 = 32747796864/(1x16)

LCM = 32747796864/16

LCM = 2046737304

Thus, we can understand that the LCM of 668,684,289,248 is 2046737304.
