Given numbers are 121,311,484,189,221

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

The LCM of 121,311,484,189,221 is 6287236956.

Find LCM of 121,311,484,189,221 with Prime Factorization

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

11 x 11 x 1 x 311 x 4 x 189 x 221 = 6287236956

Therefore, the lowest common multiple of 121,311,484,189,221 is 6287236956.

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 311 x 484 x 189 x 221 = 760755671676

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

311 : 1, 311

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

189 : 1, 3, 7, 9, 21, 27, 63, 189

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,311,484,189,221, is 1.

Now, the common factors can be found like this.

121:11x 11

311:311

484:2x 2x 11x 11

189:3x 3x 3x 7

221:13x 17

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 760755671676/(1x121)

LCM = 760755671676/121

LCM = 6287236956

Thus, we can understand that the LCM of 121,311,484,189,221 is 6287236956.
