Given numbers are 808,778,142,621

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

The LCM of 808,778,142,621 is 13858330392.

Find LCM of 808,778,142,621 with Prime Factorization

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

2 x 404 x 389 x 71 x 621 = 13858330392

Therefore, the lowest common multiple of 808,778,142,621 is 13858330392.

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.

808 x 778 x 142 x 621 = 55433321568

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.

808 : 1, 2, 4, 8, 101, 202, 404, 808

778 : 1, 2, 389, 778

142 : 1, 2, 71, 142

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 808,778,142,621, is 1.

Now, the common factors can be found like this.

808:2x 2x 2x 101

778:2x 389

142:2x 71

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 55433321568/(1x4)

LCM = 55433321568/4

LCM = 13858330392

Thus, we can understand that the LCM of 808,778,142,621 is 13858330392.
