Given numbers are 788,128,422,939

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

The LCM of 788,128,422,939 is 4996020864.

Find LCM of 788,128,422,939 with Prime Factorization

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

2 x 2 x 197 x 32 x 211 x 939 = 4996020864

Therefore, the lowest common multiple of 788,128,422,939 is 4996020864.

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.

788 x 128 x 422 x 939 = 39968166912

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.

788 : 1, 2, 4, 197, 394, 788

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

422 : 1, 2, 211, 422

939 : 1, 3, 313, 939

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,128,422,939, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

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

422:2x 211

939:3x 313

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 2 = 8

Therefore, the value for common factors is 8.

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 = 39968166912/(1x8)

LCM = 39968166912/8

LCM = 4996020864

Thus, we can understand that the LCM of 788,128,422,939 is 4996020864.
