Given numbers are 668,548,112,621

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

The LCM of 668,548,112,621 is 1591280208.

Find LCM of 668,548,112,621 with Prime Factorization

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

2 x 2 x 167 x 137 x 28 x 621 = 1591280208

Therefore, the lowest common multiple of 668,548,112,621 is 1591280208.

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 548 x 112 x 621 = 25460483328

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

548 : 1, 2, 4, 137, 274, 548

112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,548,112,621, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

548:2x 2x 137

112:2x 2x 2x 2x 7

621:3x 3x 3x 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 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 = 25460483328/(1x16)

LCM = 25460483328/16

LCM = 1591280208

Thus, we can understand that the LCM of 668,548,112,621 is 1591280208.
