Given numbers are 990,203,400,437,458

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

The LCM of 990,203,400,437,458 is 804466832400.

Find LCM of 990,203,400,437,458 with Prime Factorization

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

2 x 5 x 99 x 203 x 40 x 437 x 229 = 804466832400

Therefore, the lowest common multiple of 990,203,400,437,458 is 804466832400.

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.

990 x 203 x 400 x 437 x 458 = 16089336648000

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.

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

203 : 1, 7, 29, 203

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

437 : 1, 19, 23, 437

458 : 1, 2, 229, 458

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,203,400,437,458, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

203:7x 29

400:2x 2x 2x 2x 5x 5

437:19x 23

458:2x 229

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 5 = 20

Therefore, the value for common factors is 20.

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 = 16089336648000/(1x20)

LCM = 16089336648000/20

LCM = 804466832400

Thus, we can understand that the LCM of 990,203,400,437,458 is 804466832400.
