Given numbers are 191,203,181,455

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

The LCM of 191,203,181,455 is 456164345.

Find LCM of 191,203,181,455 with Prime Factorization

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

7 x 191 x 29 x 181 x 65 = 456164345

Therefore, the lowest common multiple of 191,203,181,455 is 456164345.

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.

191 x 203 x 181 x 455 = 3193150415

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.

191 : 1, 191

203 : 1, 7, 29, 203

181 : 1, 181

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,203,181,455, is 1.

Now, the common factors can be found like this.

191:191

203:7x 29

181:181

455:5x 7x 13

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

7 = 7

Therefore, the value for common factors is 7.

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 = 3193150415/(1x7)

LCM = 3193150415/7

LCM = 456164345

Thus, we can understand that the LCM of 191,203,181,455 is 456164345.
