Given numbers are 838,933,142,728

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

The LCM of 838,933,142,728 is 20206234776.

Find LCM of 838,933,142,728 with Prime Factorization

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

2 x 419 x 933 x 71 x 364 = 20206234776

Therefore, the lowest common multiple of 838,933,142,728 is 20206234776.

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.

838 x 933 x 142 x 728 = 80824939104

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.

838 : 1, 2, 419, 838

933 : 1, 3, 311, 933

142 : 1, 2, 71, 142

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,933,142,728, is 1.

Now, the common factors can be found like this.

838:2x 419

933:3x 311

142:2x 71

728:2x 2x 2x 7x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 80824939104/(1x4)

LCM = 80824939104/4

LCM = 20206234776

Thus, we can understand that the LCM of 838,933,142,728 is 20206234776.
