Given numbers are 645,108,550,878,865

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

The LCM of 645,108,550,878,865 is 96991913700.

Find LCM of 645,108,550,878,865 with Prime Factorization

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

2 x 3 x 5 x 43 x 18 x 55 x 439 x 173 = 96991913700

Therefore, the lowest common multiple of 645,108,550,878,865 is 96991913700.

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 108 x 550 x 878 x 865 = 29097574110000

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

108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

878 : 1, 2, 439, 878

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,108,550,878,865, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

108:2x 2x 3x 3x 3

550:2x 5x 5x 11

878:2x 439

865:5x 173

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 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 29097574110000/(1x300)

LCM = 29097574110000/300

LCM = 96991913700

Thus, we can understand that the LCM of 645,108,550,878,865 is 96991913700.
