Given numbers are 321,561,775,873,630

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

The LCM of 321,561,775,873,630 is 189526248450.

Find LCM of 321,561,775,873,630 with Prime Factorization

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

3 x 3 x 5 x 107 x 187 x 155 x 97 x 14 = 189526248450

Therefore, the lowest common multiple of 321,561,775,873,630 is 189526248450.

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 561 x 775 x 873 x 630 = 76758130622250

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

561 : 1, 3, 11, 17, 33, 51, 187, 561

775 : 1, 5, 25, 31, 155, 775

873 : 1, 3, 9, 97, 291, 873

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,561,775,873,630, is 1.

Now, the common factors can be found like this.

321:3x 107

561:3x 11x 17

775:5x 5x 31

873:3x 3x 97

630:2x 3x 3x 5x 7

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

3x 3x 3x 3x 5 = 405

Therefore, the value for common factors is 405.

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 = 76758130622250/(1x405)

LCM = 76758130622250/405

LCM = 189526248450

Thus, we can understand that the LCM of 321,561,775,873,630 is 189526248450.
