Given numbers are 111,138,687,207

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

The LCM of 111,138,687,207 is 3507822.

Find LCM of 111,138,687,207 with Prime Factorization

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

3 x 23 x 37 x 2 x 229 x 3 = 3507822

Therefore, the lowest common multiple of 111,138,687,207 is 3507822.

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.

111 x 138 x 687 x 207 = 2178357462

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.

111 : 1, 3, 37, 111

138 : 1, 2, 3, 6, 23, 46, 69, 138

687 : 1, 3, 229, 687

207 : 1, 3, 9, 23, 69, 207

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 111,138,687,207, is 3.

Now, the common factors can be found like this.

111:3x 37

138:2x 3x 23

687:3x 229

207:3x 3x 23

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

3x 3x 23 = 207

Therefore, the value for common factors is 207.

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 = 2178357462/(3x207)

LCM = 2178357462/621

LCM = 3507822

Thus, we can understand that the LCM of 111,138,687,207 is 3507822.
