Given numbers are 391,449,621

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

The LCM of 391,449,621 is 4740093.

Find LCM of 391,449,621 with Prime Factorization

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

23 x 17 x 449 x 27 = 4740093

Therefore, the lowest common multiple of 391,449,621 is 4740093.

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.

391 x 449 x 621 = 109022139

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.

391 : 1, 17, 23, 391

449 : 1, 449

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,449,621, is 1.

Now, the common factors can be found like this.

391:17x 23

449:449

621:3x 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.

23 = 23

Therefore, the value for common factors is 23.

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 = 109022139/(1x23)

LCM = 109022139/23

LCM = 4740093

Thus, we can understand that the LCM of 391,449,621 is 4740093.

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

• LCM of 429, 405, 901
