Given numbers are 728,990,460,544

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

The LCM of 728,990,460,544 is 563603040.

Find LCM of 728,990,460,544 with Prime Factorization

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

2 x 2 x 2 x 5 x 91 x 99 x 23 x 68 = 563603040

Therefore, the lowest common multiple of 728,990,460,544 is 563603040.

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.

728 x 990 x 460 x 544 = 180352972800

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

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

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,990,460,544, is 2.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

990:2x 3x 3x 5x 11

460:2x 2x 5x 23

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

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 2x 2x 2x 5 = 160

Therefore, the value for common factors is 160.

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 = 180352972800/(2x160)

LCM = 180352972800/320

LCM = 563603040

Thus, we can understand that the LCM of 728,990,460,544 is 563603040.
