Given numbers are 386,945,199,220

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

The LCM of 386,945,199,220 is 1596963060.

Find LCM of 386,945,199,220 with Prime Factorization

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

2 x 5 x 193 x 189 x 199 x 22 = 1596963060

Therefore, the lowest common multiple of 386,945,199,220 is 1596963060.

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.

386 x 945 x 199 x 220 = 15969630600

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.

386 : 1, 2, 193, 386

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

199 : 1, 199

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,945,199,220, is 1.

Now, the common factors can be found like this.

386:2x 193

945:3x 3x 3x 5x 7

199:199

220:2x 2x 5x 11

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 15969630600/(1x10)

LCM = 15969630600/10

LCM = 1596963060

Thus, we can understand that the LCM of 386,945,199,220 is 1596963060.
