Given numbers are 663,728,923

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

The LCM of 663,728,923 is 2636088.

Find LCM of 663,728,923 with Prime Factorization

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

13 x 51 x 56 x 71 = 2636088

Therefore, the lowest common multiple of 663,728,923 is 2636088.

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.

663 x 728 x 923 = 445498872

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.

663 : 1, 3, 13, 17, 39, 51, 221, 663

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

923 : 1, 13, 71, 923

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,728,923, is 13.

Now, the common factors can be found like this.

663:3x 13x 17

728:2x 2x 2x 7x 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.

13 = 13

Therefore, the value for common factors is 13.

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 = 445498872/(13x13)

LCM = 445498872/169

LCM = 2636088

Thus, we can understand that the LCM of 663,728,923 is 2636088.
