Given numbers are 990,537,720,525

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

The LCM of 990,537,720,525 is 49618800.

Find LCM of 990,537,720,525 with Prime Factorization

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

2 x 3 x 3 x 5 x 11 x 179 x 8 x 35 = 49618800

Therefore, the lowest common multiple of 990,537,720,525 is 49618800.

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 537 x 720 x 525 = 200956140000

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

537 : 1, 3, 179, 537

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,537,720,525, is 3.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

537:3x 179

720:2x 2x 2x 2x 3x 3x 5

525:3x 5x 5x 7

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 5 = 1350

Therefore, the value for common factors is 1350.

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 = 200956140000/(3x1350)

LCM = 200956140000/4050

LCM = 49618800

Thus, we can understand that the LCM of 990,537,720,525 is 49618800.
