Given numbers are 990,821,205,345,487

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

The LCM of 990,821,205,345,487 is 373266492390.

Find LCM of 990,821,205,345,487 with Prime Factorization

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

3 x 5 x 66 x 821 x 41 x 23 x 487 = 373266492390

Therefore, the lowest common multiple of 990,821,205,345,487 is 373266492390.

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 821 x 205 x 345 x 487 = 27994986929250

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

821 : 1, 821

205 : 1, 5, 41, 205

345 : 1, 3, 5, 15, 23, 69, 115, 345

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,821,205,345,487, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

821:821

205:5x 41

345:3x 5x 23

487:487

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

3x 5x 5 = 75

Therefore, the value for common factors is 75.

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 = 27994986929250/(1x75)

LCM = 27994986929250/75

LCM = 373266492390

Thus, we can understand that the LCM of 990,821,205,345,487 is 373266492390.
