Given numbers are 853,218,218,198

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

The LCM of 853,218,218,198 is 18409446.

Find LCM of 853,218,218,198 with Prime Factorization

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

2 x 109 x 853 x 1 x 1 x 99 = 18409446

Therefore, the lowest common multiple of 853,218,218,198 is 18409446.

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.

853 x 218 x 218 x 198 = 8026518456

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.

853 : 1, 853

218 : 1, 2, 109, 218

218 : 1, 2, 109, 218

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,218,218,198, is 1.

Now, the common factors can be found like this.

853:853

218:2x 109

218:2x 109

198:2x 3x 3x 11

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 109 = 436

Therefore, the value for common factors is 436.

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 = 8026518456/(1x436)

LCM = 8026518456/436

LCM = 18409446

Thus, we can understand that the LCM of 853,218,218,198 is 18409446.
