Given numbers are 221,831,778,778

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

The LCM of 221,831,778,778 is 142880478.

Find LCM of 221,831,778,778 with Prime Factorization

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

2 x 389 x 221 x 831 x 1 x 1 = 142880478

Therefore, the lowest common multiple of 221,831,778,778 is 142880478.

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.

221 x 831 x 778 x 778 = 111161011884

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.

221 : 1, 13, 17, 221

831 : 1, 3, 277, 831

778 : 1, 2, 389, 778

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,831,778,778, is 1.

Now, the common factors can be found like this.

221:13x 17

831:3x 277

778:2x 389

778:2x 389

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 389 = 778

Therefore, the value for common factors is 778.

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 = 111161011884/(1x778)

LCM = 111161011884/778

LCM = 142880478

Thus, we can understand that the LCM of 221,831,778,778 is 142880478.
