Given numbers are 128,121,270,866,470

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

The LCM of 128,121,270,866,470 is 42551498880.

Find LCM of 128,121,270,866,470 with Prime Factorization

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

2 x 5 x 64 x 121 x 27 x 433 x 47 = 42551498880

Therefore, the lowest common multiple of 128,121,270,866,470 is 42551498880.

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 121 x 270 x 866 x 470 = 1702059955200

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

121 : 1, 11, 121

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

866 : 1, 2, 433, 866

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,121,270,866,470, is 1.

Now, the common factors can be found like this.

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

121:11x 11

270:2x 3x 3x 3x 5

866:2x 433

470:2x 5x 47

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 5 = 40

Therefore, the value for common factors is 40.

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 = 1702059955200/(1x40)

LCM = 1702059955200/40

LCM = 42551498880

Thus, we can understand that the LCM of 128,121,270,866,470 is 42551498880.
