Calculate the LCM of 231,831,173,286

Given numbers are 231,831,173,286

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

The LCM of 231,831,173,286 is 287813526.

Find LCM of 231,831,173,286 with Prime Factorization


3 231, 831, 173, 286
11 77, 277, 173, 286
7, 277, 173, 26

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

3 x 11 x 7 x 277 x 173 x 26 = 287813526

Therefore, the lowest common multiple of 231,831,173,286 is 287813526.

LCM Formula to Find Lowest Common Multiple of 231,831,173,286

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.

231 x 831 x 173 x 286 = 9497846358

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.

231 : 1, 3, 7, 11, 21, 33, 77, 231

831 : 1, 3, 277, 831

173 : 1, 173

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,831,173,286, is 1.

Now, the common factors can be found like this.

231:3x 7x 11

831:3x 277

173:173

286:2x 11x 13

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

3x 11 = 33

Therefore, the value for common factors is 33.

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 = 9497846358/(1x33)

LCM = 9497846358/33

LCM = 287813526

Thus, we can understand that the LCM of 231,831,173,286 is 287813526.
