Given numbers are 668,646,214,480

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

The LCM of 668,646,214,480 is 2770409760.

Find LCM of 668,646,214,480 with Prime Factorization

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

2 x 2 x 167 x 323 x 107 x 120 = 2770409760

Therefore, the lowest common multiple of 668,646,214,480 is 2770409760.

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 646 x 214 x 480 = 44326556160

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

214 : 1, 2, 107, 214

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,646,214,480, is 2.

Now, the common factors can be found like this.

668:2x 2x 167

646:2x 17x 19

214:2x 107

480:2x 2x 2x 2x 2x 3x 5

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 2 = 8

Therefore, the value for common factors is 8.

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 = 44326556160/(2x8)

LCM = 44326556160/16

LCM = 2770409760

Thus, we can understand that the LCM of 668,646,214,480 is 2770409760.
