Given numbers are 660,808,618,935,561

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

The LCM of 660,808,618,935,561 is 233443320.

Find LCM of 660,808,618,935,561 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 17 x 1 x 202 x 103 x 1 x 1 = 233443320

Therefore, the lowest common multiple of 660,808,618,935,561 is 233443320.

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.

660 x 808 x 618 x 935 x 561 = 172869447326400

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

808 : 1, 2, 4, 8, 101, 202, 404, 808

618 : 1, 2, 3, 6, 103, 206, 309, 618

935 : 1, 5, 11, 17, 55, 85, 187, 935

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,808,618,935,561, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

808:2x 2x 2x 101

618:2x 3x 103

935:5x 11x 17

561:3x 11x 17

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 3x 3x 5x 11x 11x 17 = 740520

Therefore, the value for common factors is 740520.

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 = 172869447326400/(1x740520)

LCM = 172869447326400/740520

LCM = 233443320

Thus, we can understand that the LCM of 660,808,618,935,561 is 233443320.
