Given numbers are 218,453,345,621

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

The LCM of 218,453,345,621 is 102210390.

Find LCM of 218,453,345,621 with Prime Factorization

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

3 x 23 x 218 x 151 x 5 x 9 = 102210390

Therefore, the lowest common multiple of 218,453,345,621 is 102210390.

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.

218 x 453 x 345 x 621 = 21157550730

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.

218 : 1, 2, 109, 218

453 : 1, 3, 151, 453

345 : 1, 3, 5, 15, 23, 69, 115, 345

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 218,453,345,621, is 1.

Now, the common factors can be found like this.

218:2x 109

453:3x 151

345:3x 5x 23

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.

3x 3x 23 = 207

Therefore, the value for common factors is 207.

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 = 21157550730/(1x207)

LCM = 21157550730/207

LCM = 102210390

Thus, we can understand that the LCM of 218,453,345,621 is 102210390.
