Given numbers are 990,481,889,660,981

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

The LCM of 990,481,889,660,981 is 92286574380.

Find LCM of 990,481,889,660,981 with Prime Factorization

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

2 x 3 x 3 x 5 x 11 x 1 x 481 x 889 x 2 x 109 = 92286574380

Therefore, the lowest common multiple of 990,481,889,660,981 is 92286574380.

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 481 x 889 x 660 x 981 = 274091125908600

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

481 : 1, 13, 37, 481

889 : 1, 7, 127, 889

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,481,889,660,981, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

481:13x 37

889:7x 127

660:2x 2x 3x 5x 11

981:3x 3x 109

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

2x 3x 3x 3x 5x 11 = 2970

Therefore, the value for common factors is 2970.

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 = 274091125908600/(1x2970)

LCM = 274091125908600/2970

LCM = 92286574380

Thus, we can understand that the LCM of 990,481,889,660,981 is 92286574380.
