The LCM of 223,891,198,218 is 43315074.

Find LCM of 223,891,198,218 with Prime Factorization


2 223, 891, 198, 218
3 223, 891, 99, 109
3 223, 297, 33, 109
11 223, 99, 11, 109
223, 9, 1, 109

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

2 x 3 x 3 x 11 x 223 x 9 x 1 x 109 = 43315074

Therefore, the lowest common multiple of 223,891,198,218 is 43315074.

LCM Formula to Find Lowest Common Multiple of 223,891,198,218

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.

223 x 891 x 198 x 218 = 8576384652

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.

223 : 1, 223

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

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

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,891,198,218, is 1.

Now, the common factors can be found like this.

223:223

891:3x 3x 3x 3x 11

198:2x 3x 3x 11

218:2x 109

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

2x 3x 3x 11 = 198

Therefore, the value for common factors is 198.

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 = 8576384652/(1x198)

LCM = 8576384652/198

LCM = 43315074

Thus, we can understand that the LCM of 223,891,198,218 is 43315074.
