Given numbers are 728,728,787,805

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

The LCM of 728,728,787,805 is 65887640.

Find LCM of 728,728,787,805 with Prime Factorization

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

2 x 2 x 2 x 7 x 13 x 1 x 1 x 787 x 115 = 65887640

Therefore, the lowest common multiple of 728,728,787,805 is 65887640.

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 728 x 787 x 805 = 335763413440

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

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

787 : 1, 787

805 : 1, 5, 7, 23, 35, 115, 161, 805

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,728,787,805, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

728:2x 2x 2x 7x 13

787:787

805:5x 7x 23

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 7x 7x 13 = 5096

Therefore, the value for common factors is 5096.

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 = 335763413440/(1x5096)

LCM = 335763413440/5096

LCM = 65887640

Thus, we can understand that the LCM of 728,728,787,805 is 65887640.
