Given numbers are 389,778,738,418

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

The LCM of 389,778,738,418 is 60000138.

Find LCM of 389,778,738,418 with Prime Factorization

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

2 x 389 x 1 x 1 x 369 x 209 = 60000138

Therefore, the lowest common multiple of 389,778,738,418 is 60000138.

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.

389 x 778 x 738 x 418 = 93360214728

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.

389 : 1, 389

778 : 1, 2, 389, 778

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,778,738,418, is 1.

Now, the common factors can be found like this.

389:389

778:2x 389

738:2x 3x 3x 41

418:2x 11x 19

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 389 = 1556

Therefore, the value for common factors is 1556.

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 = 93360214728/(1x1556)

LCM = 93360214728/1556

LCM = 60000138

Thus, we can understand that the LCM of 389,778,738,418 is 60000138.
