Given numbers are 668,138,813,981

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

The LCM of 668,138,813,981 is 4084534764.

Find LCM of 668,138,813,981 with Prime Factorization

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

2 x 3 x 334 x 23 x 271 x 327 = 4084534764

Therefore, the lowest common multiple of 668,138,813,981 is 4084534764.

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 138 x 813 x 981 = 73521625752

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

813 : 1, 3, 271, 813

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,138,813,981, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

138:2x 3x 23

813:3x 271

981:3x 3x 109

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 73521625752/(1x18)

LCM = 73521625752/18

LCM = 4084534764

Thus, we can understand that the LCM of 668,138,813,981 is 4084534764.
