Given numbers are 622,408,305,973,998

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

The LCM of 622,408,305,973,998 is 18790302742680.

Find LCM of 622,408,305,973,998 with Prime Factorization

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

2 x 311 x 204 x 305 x 973 x 499 = 18790302742680

Therefore, the lowest common multiple of 622,408,305,973,998 is 18790302742680.

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.

622 x 408 x 305 x 973 x 998 = 75161210970720

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.

622 : 1, 2, 311, 622

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

305 : 1, 5, 61, 305

973 : 1, 7, 139, 973

998 : 1, 2, 499, 998

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,408,305,973,998, is 1.

Now, the common factors can be found like this.

622:2x 311

408:2x 2x 2x 3x 17

305:5x 61

973:7x 139

998:2x 499

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 75161210970720/(1x4)

LCM = 75161210970720/4

LCM = 18790302742680

Thus, we can understand that the LCM of 622,408,305,973,998 is 18790302742680.
