Given numbers are 546,330,345,990

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

The LCM of 546,330,345,990 is 2072070.

Find LCM of 546,330,345,990 with Prime Factorization

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

2 x 3 x 5 x 11 x 91 x 1 x 23 x 3 = 2072070

Therefore, the lowest common multiple of 546,330,345,990 is 2072070.

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.

546 x 330 x 345 x 990 = 61540479000

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.

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

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

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

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,330,345,990, is 3.

Now, the common factors can be found like this.

546:2x 3x 7x 13

330:2x 3x 5x 11

345:3x 5x 23

990:2x 3x 3x 5x 11

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 3x 5x 5x 11 = 9900

Therefore, the value for common factors is 9900.

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 = 61540479000/(3x9900)

LCM = 61540479000/29700

LCM = 2072070

Thus, we can understand that the LCM of 546,330,345,990 is 2072070.
