Given numbers are 891,161,313,920

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

The LCM of 891,161,313,920 is 1796006520.

Find LCM of 891,161,313,920 with Prime Factorization

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

23 x 891 x 7 x 313 x 40 = 1796006520

Therefore, the lowest common multiple of 891,161,313,920 is 1796006520.

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.

891 x 161 x 313 x 920 = 41308149960

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

161 : 1, 7, 23, 161

313 : 1, 313

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 891,161,313,920, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

161:7x 23

313:313

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 = 41308149960/(1x23)

LCM = 41308149960/23

LCM = 1796006520

Thus, we can understand that the LCM of 891,161,313,920 is 1796006520.
