Given numbers are 221,386,628,778

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

The LCM of 221,386,628,778 is 10419786676.

Find LCM of 221,386,628,778 with Prime Factorization

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

2 x 221 x 193 x 314 x 389 = 10419786676

Therefore, the lowest common multiple of 221,386,628,778 is 10419786676.

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 386 x 628 x 778 = 41679146704

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

386 : 1, 2, 193, 386

628 : 1, 2, 4, 157, 314, 628

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,386,628,778, is 1.

Now, the common factors can be found like this.

221:13x 17

386:2x 193

628:2x 2x 157

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 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 = 41679146704/(1x4)

LCM = 41679146704/4

LCM = 10419786676

Thus, we can understand that the LCM of 221,386,628,778 is 10419786676.
