Given numbers are 442,494,128,923

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

The LCM of 442,494,128,923 is 38160512.

Find LCM of 442,494,128,923 with Prime Factorization

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

2 x 13 x 17 x 19 x 64 x 71 = 38160512

Therefore, the lowest common multiple of 442,494,128,923 is 38160512.

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.

442 x 494 x 128 x 923 = 25796506112

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

494 : 1, 2, 13, 19, 26, 38, 247, 494

128 : 1, 2, 4, 8, 16, 32, 64, 128

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,494,128,923, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

494:2x 13x 19

128:2x 2x 2x 2x 2x 2x 2

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.

2x 2x 13x 13 = 676

Therefore, the value for common factors is 676.

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 = 25796506112/(1x676)

LCM = 25796506112/676

LCM = 38160512

Thus, we can understand that the LCM of 442,494,128,923 is 38160512.
