Given numbers are 990,993,247,305

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

The LCM of 990,993,247,305 is 4937305230.

Find LCM of 990,993,247,305 with Prime Factorization

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

3 x 5 x 66 x 331 x 247 x 61 = 4937305230

Therefore, the lowest common multiple of 990,993,247,305 is 4937305230.

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 993 x 247 x 305 = 74059578450

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

993 : 1, 3, 331, 993

247 : 1, 13, 19, 247

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,993,247,305, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

993:3x 331

247:13x 19

305:5x 61

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 = 74059578450/(1x15)

LCM = 74059578450/15

LCM = 4937305230

Thus, we can understand that the LCM of 990,993,247,305 is 4937305230.
