Given numbers are 789,515,789,981

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

The LCM of 789,515,789,981 is 132871545.

Find LCM of 789,515,789,981 with Prime Factorization

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

3 x 263 x 1 x 515 x 1 x 327 = 132871545

Therefore, the lowest common multiple of 789,515,789,981 is 132871545.

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.

789 x 515 x 789 x 981 = 314506947015

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.

789 : 1, 3, 263, 789

515 : 1, 5, 103, 515

789 : 1, 3, 263, 789

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,515,789,981, is 1.

Now, the common factors can be found like this.

789:3x 263

515:5x 103

789:3x 263

981:3x 3x 109

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3x 263 = 2367

Therefore, the value for common factors is 2367.

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 = 314506947015/(1x2367)

LCM = 314506947015/2367

LCM = 132871545

Thus, we can understand that the LCM of 789,515,789,981 is 132871545.
