Given numbers are 181,764,540,422,646

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

The LCM of 181,764,540,422,646 is 1272303376020.

Find LCM of 181,764,540,422,646 with Prime Factorization

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

2 x 2 x 181 x 191 x 135 x 211 x 323 = 1272303376020

Therefore, the lowest common multiple of 181,764,540,422,646 is 1272303376020.

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.

181 x 764 x 540 x 422 x 646 = 20356854016320

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.

181 : 1, 181

764 : 1, 2, 4, 191, 382, 764

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

422 : 1, 2, 211, 422

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,764,540,422,646, is 1.

Now, the common factors can be found like this.

181:181

764:2x 2x 191

540:2x 2x 3x 3x 3x 5

422:2x 211

646:2x 17x 19

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 2 = 16

Therefore, the value for common factors is 16.

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 = 20356854016320/(1x16)

LCM = 20356854016320/16

LCM = 1272303376020

Thus, we can understand that the LCM of 181,764,540,422,646 is 1272303376020.
