Given numbers are 660,385,621,327,445

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

The LCM of 660,385,621,327,445 is 9277454340.

Find LCM of 660,385,621,327,445 with Prime Factorization

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

3 x 5 x 11 x 4 x 7 x 207 x 109 x 89 = 9277454340

Therefore, the lowest common multiple of 660,385,621,327,445 is 9277454340.

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 385 x 621 x 327 x 445 = 22961699491500

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

385 : 1, 5, 7, 11, 35, 55, 77, 385

621 : 1, 3, 9, 23, 27, 69, 207, 621

327 : 1, 3, 109, 327

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,385,621,327,445, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

385:5x 7x 11

621:3x 3x 3x 23

327:3x 109

445:5x 89

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

3x 3x 5x 5x 11 = 2475

Therefore, the value for common factors is 2475.

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 = 22961699491500/(1x2475)

LCM = 22961699491500/2475

LCM = 9277454340

Thus, we can understand that the LCM of 660,385,621,327,445 is 9277454340.
