Given numbers are 728,942,305,676

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

The LCM of 728,942,305,676 is 1359550920.

Find LCM of 728,942,305,676 with Prime Factorization

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

2 x 2 x 13 x 14 x 471 x 305 x 13 = 1359550920

Therefore, the lowest common multiple of 728,942,305,676 is 1359550920.

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 942 x 305 x 676 = 141393295680

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

942 : 1, 2, 3, 6, 157, 314, 471, 942

305 : 1, 5, 61, 305

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,942,305,676, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

942:2x 3x 157

305:5x 61

676:2x 2x 13x 13

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 13 = 104

Therefore, the value for common factors is 104.

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 = 141393295680/(1x104)

LCM = 141393295680/104

LCM = 1359550920

Thus, we can understand that the LCM of 728,942,305,676 is 1359550920.
