Given numbers are 321,221,818,660

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

The LCM of 321,221,818,660 is 6383271180.

Find LCM of 321,221,818,660 with Prime Factorization

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

2 x 3 x 107 x 221 x 409 x 110 = 6383271180

Therefore, the lowest common multiple of 321,221,818,660 is 6383271180.

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.

321 x 221 x 818 x 660 = 38299627080

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.

321 : 1, 3, 107, 321

221 : 1, 13, 17, 221

818 : 1, 2, 409, 818

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,221,818,660, is 1.

Now, the common factors can be found like this.

321:3x 107

221:13x 17

818:2x 409

660:2x 2x 3x 5x 11

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 38299627080/(1x6)

LCM = 38299627080/6

LCM = 6383271180

Thus, we can understand that the LCM of 321,221,818,660 is 6383271180.
