Given numbers are 990,345,552,437

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

The LCM of 990,345,552,437 is 1730520.

Find LCM of 990,345,552,437 with Prime Factorization

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

2 x 3 x 5 x 23 x 33 x 1 x 4 x 19 = 1730520

Therefore, the lowest common multiple of 990,345,552,437 is 1730520.

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 345 x 552 x 437 = 82390057200

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

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

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

437 : 1, 19, 23, 437

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,345,552,437, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

345:3x 5x 23

552:2x 2x 2x 3x 23

437:19x 23

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 5x 23x 23 = 47610

Therefore, the value for common factors is 47610.

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 = 82390057200/(1x47610)

LCM = 82390057200/47610

LCM = 1730520

Thus, we can understand that the LCM of 990,345,552,437 is 1730520.
