Given numbers are 395,920,138,912,389

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

The LCM of 395,920,138,912,389 is 3223067280.

Find LCM of 395,920,138,912,389 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 23 x 79 x 1 x 1 x 38 x 389 = 3223067280

Therefore, the lowest common multiple of 395,920,138,912,389 is 3223067280.

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.

395 x 920 x 138 x 912 x 389 = 17791331385600

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.

395 : 1, 5, 79, 395

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

138 : 1, 2, 3, 6, 23, 46, 69, 138

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,920,138,912,389, is 1.

Now, the common factors can be found like this.

395:5x 79

920:2x 2x 2x 5x 23

138:2x 3x 23

912:2x 2x 2x 2x 3x 19

389:389

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 2x 3x 5x 23 = 5520

Therefore, the value for common factors is 5520.

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 = 17791331385600/(1x5520)

LCM = 17791331385600/5520

LCM = 3223067280

Thus, we can understand that the LCM of 395,920,138,912,389 is 3223067280.
