Given numbers are 728,149,585,923

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

The LCM of 728,149,585,923 is 346568040.

Find LCM of 728,149,585,923 with Prime Factorization

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

13 x 56 x 149 x 45 x 71 = 346568040

Therefore, the lowest common multiple of 728,149,585,923 is 346568040.

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 149 x 585 x 923 = 58569998760

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

149 : 1, 149

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,149,585,923, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

149:149

585:3x 3x 5x 13

923:13x 71

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 58569998760/(1x169)

LCM = 58569998760/169

LCM = 346568040

Thus, we can understand that the LCM of 728,149,585,923 is 346568040.
