Given numbers are 321,445,406,856

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

The LCM of 321,445,406,856 is 231980280.

Find LCM of 321,445,406,856 with Prime Factorization

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

2 x 107 x 3 x 445 x 203 x 4 = 231980280

Therefore, the lowest common multiple of 321,445,406,856 is 231980280.

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 445 x 406 x 856 = 49643779920

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

445 : 1, 5, 89, 445

406 : 1, 2, 7, 14, 29, 58, 203, 406

856 : 1, 2, 4, 8, 107, 214, 428, 856

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,445,406,856, is 1.

Now, the common factors can be found like this.

321:3x 107

445:5x 89

406:2x 7x 29

856:2x 2x 2x 107

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

2x 107 = 214

Therefore, the value for common factors is 214.

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 = 49643779920/(1x214)

LCM = 49643779920/214

LCM = 231980280

Thus, we can understand that the LCM of 321,445,406,856 is 231980280.
