Given numbers are 728,361,343,446

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

The LCM of 728,361,343,446 is 2871703016.

Find LCM of 728,361,343,446 with Prime Factorization

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

2 x 7 x 52 x 361 x 49 x 223 = 2871703016

Therefore, the lowest common multiple of 728,361,343,446 is 2871703016.

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 361 x 343 x 446 = 40203842224

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

361 : 1, 19, 361

343 : 1, 7, 49, 343

446 : 1, 2, 223, 446

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,361,343,446, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

361:19x 19

343:7x 7x 7

446:2x 223

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 40203842224/(1x14)

LCM = 40203842224/14

LCM = 2871703016

Thus, we can understand that the LCM of 728,361,343,446 is 2871703016.
