Given numbers are 621,317,920

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

The LCM of 621,317,920 is 7874280.

Find LCM of 621,317,920 with Prime Factorization

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

23 x 27 x 317 x 40 = 7874280

Therefore, the lowest common multiple of 621,317,920 is 7874280.

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.

621 x 317 x 920 = 181108440

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.

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

317 : 1, 317

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,317,920, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

317:317

920:2x 2x 2x 5x 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 = 181108440/(1x23)

LCM = 181108440/23

LCM = 7874280

Thus, we can understand that the LCM of 621,317,920 is 7874280.
