Given numbers are 121,193,311,579

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

The LCM of 121,193,311,579 is 21788349.

Find LCM of 121,193,311,579 with Prime Factorization

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

193 x 121 x 1 x 311 x 3 = 21788349

Therefore, the lowest common multiple of 121,193,311,579 is 21788349.

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.

121 x 193 x 311 x 579 = 4205151357

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.

121 : 1, 11, 121

193 : 1, 193

311 : 1, 311

579 : 1, 3, 193, 579

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,193,311,579, is 1.

Now, the common factors can be found like this.

121:11x 11

193:193

311:311

579:3x 193

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

193 = 193

Therefore, the value for common factors is 193.

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 = 4205151357/(1x193)

LCM = 4205151357/193

LCM = 21788349

Thus, we can understand that the LCM of 121,193,311,579 is 21788349.
