Given numbers are 128,936,940,516,842

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

The LCM of 128,936,940,516,842 is 63710974080.

Find LCM of 128,936,940,516,842 with Prime Factorization

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

2 x 2 x 2 x 3 x 16 x 39 x 235 x 43 x 421 = 63710974080

Therefore, the lowest common multiple of 128,936,940,516,842 is 63710974080.

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.

128 x 936 x 940 x 516 x 842 = 48930028093440

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.

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

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

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

842 : 1, 2, 421, 842

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,936,940,516,842, is 2.

Now, the common factors can be found like this.

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

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

940:2x 2x 5x 47

516:2x 2x 3x 43

842:2x 421

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 2x 2x 2x 2x 2x 3 = 384

Therefore, the value for common factors is 384.

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 = 48930028093440/(2x384)

LCM = 48930028093440/768

LCM = 63710974080

Thus, we can understand that the LCM of 128,936,940,516,842 is 63710974080.
