Given numbers are 286,198,121,203

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

The LCM of 286,198,121,203 is 5747742.

Find LCM of 286,198,121,203 with Prime Factorization

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

2 x 11 x 13 x 9 x 11 x 203 = 5747742

Therefore, the lowest common multiple of 286,198,121,203 is 5747742.

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.

286 x 198 x 121 x 203 = 1390953564

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.

286 : 1, 2, 11, 13, 22, 26, 143, 286

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

121 : 1, 11, 121

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,198,121,203, is 1.

Now, the common factors can be found like this.

286:2x 11x 13

198:2x 3x 3x 11

121:11x 11

203:7x 29

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

2x 11x 11 = 242

Therefore, the value for common factors is 242.

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 = 1390953564/(1x242)

LCM = 1390953564/242

LCM = 5747742

Thus, we can understand that the LCM of 286,198,121,203 is 5747742.
