Given numbers are 990,544,402,489

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

The LCM of 990,544,402,489 is 2940806880.

Find LCM of 990,544,402,489 with Prime Factorization

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

2 x 3 x 165 x 272 x 67 x 163 = 2940806880

Therefore, the lowest common multiple of 990,544,402,489 is 2940806880.

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 544 x 402 x 489 = 105869047680

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

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

402 : 1, 2, 3, 6, 67, 134, 201, 402

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,544,402,489, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

544:2x 2x 2x 2x 2x 17

402:2x 3x 67

489:3x 163

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 105869047680/(1x36)

LCM = 105869047680/36

LCM = 2940806880

Thus, we can understand that the LCM of 990,544,402,489 is 2940806880.
