Given numbers are 311,764,228,221

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

The LCM of 311,764,228,221 is 2993097588.

Find LCM of 311,764,228,221 with Prime Factorization

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

2 x 2 x 311 x 191 x 57 x 221 = 2993097588

Therefore, the lowest common multiple of 311,764,228,221 is 2993097588.

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.

311 x 764 x 228 x 221 = 11972390352

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.

311 : 1, 311

764 : 1, 2, 4, 191, 382, 764

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,764,228,221, is 1.

Now, the common factors can be found like this.

311:311

764:2x 2x 191

228:2x 2x 3x 19

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 11972390352/(1x4)

LCM = 11972390352/4

LCM = 2993097588

Thus, we can understand that the LCM of 311,764,228,221 is 2993097588.
