Given numbers are 687,223,105

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

The LCM of 687,223,105 is 5362035.

Find LCM of 687,223,105 with Prime Factorization

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

3 x 229 x 223 x 35 = 5362035

Therefore, the lowest common multiple of 687,223,105 is 5362035.

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.

687 x 223 x 105 = 16086105

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.

687 : 1, 3, 229, 687

223 : 1, 223

105 : 1, 3, 5, 7, 15, 21, 35, 105

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,223,105, is 1.

Now, the common factors can be found like this.

687:3x 229

223:223

105:3x 5x 7

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 = 16086105/(1x3)

LCM = 16086105/3

LCM = 5362035

Thus, we can understand that the LCM of 687,223,105 is 5362035.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 993, 534, 575
• LCM of 961, 673, 380
