Given numbers are 272,888,638,865

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

The LCM of 272,888,638,865 is 8331029520.

Find LCM of 272,888,638,865 with Prime Factorization

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

2 x 2 x 2 x 34 x 111 x 319 x 865 = 8331029520

Therefore, the lowest common multiple of 272,888,638,865 is 8331029520.

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.

272 x 888 x 638 x 865 = 133296472320

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.

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

638 : 1, 2, 11, 22, 29, 58, 319, 638

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,888,638,865, is 1.

Now, the common factors can be found like this.

272:2x 2x 2x 2x 17

888:2x 2x 2x 3x 37

638:2x 11x 29

865:5x 173

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 2 = 16

Therefore, the value for common factors is 16.

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 = 133296472320/(1x16)

LCM = 133296472320/16

LCM = 8331029520

Thus, we can understand that the LCM of 272,888,638,865 is 8331029520.
