Given numbers are 198,622,568,815

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

The LCM of 198,622,568,815 is 14252843880.

Find LCM of 198,622,568,815 with Prime Factorization

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

2 x 99 x 311 x 284 x 815 = 14252843880

Therefore, the lowest common multiple of 198,622,568,815 is 14252843880.

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.

198 x 622 x 568 x 815 = 57011375520

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.

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

622 : 1, 2, 311, 622

568 : 1, 2, 4, 8, 71, 142, 284, 568

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,622,568,815, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

622:2x 311

568:2x 2x 2x 71

815:5x 163

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 = 57011375520/(1x4)

LCM = 57011375520/4

LCM = 14252843880

Thus, we can understand that the LCM of 198,622,568,815 is 14252843880.
