Given numbers are 128,240,201,230,556

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

The LCM of 128,240,201,230,556 is 411262080.

Find LCM of 128,240,201,230,556 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 5 x 8 x 1 x 67 x 23 x 139 = 411262080

Therefore, the lowest common multiple of 128,240,201,230,556 is 411262080.

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.

128 x 240 x 201 x 230 x 556 = 789623193600

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

201 : 1, 3, 67, 201

230 : 1, 2, 5, 10, 23, 46, 115, 230

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,240,201,230,556, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

240:2x 2x 2x 2x 3x 5

201:3x 67

230:2x 5x 23

556:2x 2x 139

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 2x 2x 2x 3x 5 = 1920

Therefore, the value for common factors is 1920.

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 = 789623193600/(1x1920)

LCM = 789623193600/1920

LCM = 411262080

Thus, we can understand that the LCM of 128,240,201,230,556 is 411262080.
