Given numbers are 645,625,396,681,880

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

The LCM of 645,625,396,681,880 is 9663390000.

Find LCM of 645,625,396,681,880 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 43 x 125 x 3 x 227 x 4 = 9663390000

Therefore, the lowest common multiple of 645,625,396,681,880 is 9663390000.

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.

645 x 625 x 396 x 681 x 880 = 95667561000000

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

625 : 1, 5, 25, 125, 625

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

681 : 1, 3, 227, 681

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,625,396,681,880, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

625:5x 5x 5x 5

396:2x 2x 3x 3x 11

681:3x 227

880:2x 2x 2x 2x 5x 11

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 3x 3x 5x 5x 11 = 9900

Therefore, the value for common factors is 9900.

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 = 95667561000000/(1x9900)

LCM = 95667561000000/9900

LCM = 9663390000

Thus, we can understand that the LCM of 645,625,396,681,880 is 9663390000.
