Given numbers are 321,971,180,755

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

The LCM of 321,971,180,755 is 2823920460.

Find LCM of 321,971,180,755 with Prime Factorization

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

3 x 5 x 107 x 971 x 12 x 151 = 2823920460

Therefore, the lowest common multiple of 321,971,180,755 is 2823920460.

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 971 x 180 x 755 = 42358806900

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

971 : 1, 971

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

755 : 1, 5, 151, 755

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,971,180,755, is 1.

Now, the common factors can be found like this.

321:3x 107

971:971

180:2x 2x 3x 3x 5

755:5x 151

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 42358806900/(1x15)

LCM = 42358806900/15

LCM = 2823920460

Thus, we can understand that the LCM of 321,971,180,755 is 2823920460.
