Given numbers are 789,439,788,642

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

The LCM of 789,439,788,642 is 29204617236.

Find LCM of 789,439,788,642 with Prime Factorization

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

2 x 3 x 263 x 439 x 394 x 107 = 29204617236

Therefore, the lowest common multiple of 789,439,788,642 is 29204617236.

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 439 x 788 x 642 = 175227703416

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

439 : 1, 439

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,439,788,642, is 1.

Now, the common factors can be found like this.

789:3x 263

439:439

788:2x 2x 197

642:2x 3x 107

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 175227703416/(1x6)

LCM = 175227703416/6

LCM = 29204617236

Thus, we can understand that the LCM of 789,439,788,642 is 29204617236.
