Given numbers are 440,417,687

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

The LCM of 440,417,687 is 42016920.

Find LCM of 440,417,687 with Prime Factorization

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

3 x 440 x 139 x 229 = 42016920

Therefore, the lowest common multiple of 440,417,687 is 42016920.

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.

440 x 417 x 687 = 126050760

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.

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

417 : 1, 3, 139, 417

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,417,687, is 1.

Now, the common factors can be found like this.

440:2x 2x 2x 5x 11

417:3x 139

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.

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 = 126050760/(1x3)

LCM = 126050760/3

LCM = 42016920

Thus, we can understand that the LCM of 440,417,687 is 42016920.

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

• LCM of 275, 286, 707
