Given numbers are 231,306,989,687

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

The LCM of 231,306,989,687 is 5336345322.

Find LCM of 231,306,989,687 with Prime Factorization

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

3 x 77 x 102 x 989 x 229 = 5336345322

Therefore, the lowest common multiple of 231,306,989,687 is 5336345322.

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 306 x 989 x 687 = 48027107898

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

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

989 : 1, 23, 43, 989

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,306,989,687, is 1.

Now, the common factors can be found like this.

231:3x 7x 11

306:2x 3x 3x 17

989:23x 43

687:3x 229

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 48027107898/(1x9)

LCM = 48027107898/9

LCM = 5336345322

Thus, we can understand that the LCM of 231,306,989,687 is 5336345322.
