The LCM of 287,853,345,432 is 12162210480.

Find LCM of 287,853,345,432 with Prime Factorization


3 287, 853, 345, 432
287, 853, 115, 144

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

3 x 287 x 853 x 115 x 144 = 12162210480

Therefore, the lowest common multiple of 287,853,345,432 is 12162210480.

LCM Formula to Find Lowest Common Multiple of 287,853,345,432

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.

287 x 853 x 345 x 432 = 36486631440

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.

287 : 1, 7, 41, 287

853 : 1, 853

345 : 1, 3, 5, 15, 23, 69, 115, 345

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,853,345,432, is 1.

Now, the common factors can be found like this.

287:7x 41

853:853

345:3x 5x 23

432:2x 2x 2x 2x 3x 3x 3

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

3 = 3

Therefore, the value for common factors is 3.

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 = 36486631440/(1x3)

LCM = 36486631440/3

LCM = 12162210480

Thus, we can understand that the LCM of 287,853,345,432 is 12162210480.
