Given numbers are 405,936,783,939

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

The LCM of 405,936,783,939 is 382323240.

Find LCM of 405,936,783,939 with Prime Factorization

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

3 x 3 x 3 x 15 x 104 x 29 x 313 = 382323240

Therefore, the lowest common multiple of 405,936,783,939 is 382323240.

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.

405 x 936 x 783 x 939 = 278713641960

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.

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

783 : 1, 3, 9, 27, 29, 87, 261, 783

939 : 1, 3, 313, 939

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,936,783,939, is 3.

Now, the common factors can be found like this.

405:3x 3x 3x 3x 5

936:2x 2x 2x 3x 3x 13

783:3x 3x 3x 29

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.

3x 3x 3x 3x 3 = 243

Therefore, the value for common factors is 243.

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 = 278713641960/(3x243)

LCM = 278713641960/729

LCM = 382323240

Thus, we can understand that the LCM of 405,936,783,939 is 382323240.
