Given numbers are 990,139,325,391

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

The LCM of 990,139,325,391 is 3497358150.

Find LCM of 990,139,325,391 with Prime Factorization

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

5 x 198 x 139 x 65 x 391 = 3497358150

Therefore, the lowest common multiple of 990,139,325,391 is 3497358150.

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.

990 x 139 x 325 x 391 = 17486790750

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.

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

139 : 1, 139

325 : 1, 5, 13, 25, 65, 325

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,139,325,391, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

139:139

325:5x 5x 13

391:17x 23

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

5 = 5

Therefore, the value for common factors is 5.

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 = 17486790750/(1x5)

LCM = 17486790750/5

LCM = 3497358150

Thus, we can understand that the LCM of 990,139,325,391 is 3497358150.
