Given numbers are 163,556,556,320

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

The LCM of 163,556,556,320 is 7250240.

Find LCM of 163,556,556,320 with Prime Factorization

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

2 x 2 x 139 x 163 x 1 x 1 x 80 = 7250240

Therefore, the lowest common multiple of 163,556,556,320 is 7250240.

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.

163 x 556 x 556 x 320 = 16124533760

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.

163 : 1, 163

556 : 1, 2, 4, 139, 278, 556

556 : 1, 2, 4, 139, 278, 556

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,556,556,320, is 1.

Now, the common factors can be found like this.

163:163

556:2x 2x 139

556:2x 2x 139

320:2x 2x 2x 2x 2x 2x 5

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

2x 2x 2x 2x 139 = 2224

Therefore, the value for common factors is 2224.

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 = 16124533760/(1x2224)

LCM = 16124533760/2224

LCM = 7250240

Thus, we can understand that the LCM of 163,556,556,320 is 7250240.
