Given numbers are 645,806,515,950,680

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

The LCM of 645,806,515,950,680 is 345911100600.

Find LCM of 645,806,515,950,680 with Prime Factorization

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

2 x 5 x 129 x 403 x 103 x 95 x 68 = 345911100600

Therefore, the lowest common multiple of 645,806,515,950,680 is 345911100600.

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 806 x 515 x 950 x 680 = 172955550300000

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

806 : 1, 2, 13, 26, 31, 62, 403, 806

515 : 1, 5, 103, 515

950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,806,515,950,680, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

806:2x 13x 31

515:5x 103

950:2x 5x 5x 19

680:2x 2x 2x 5x 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 5x 5x 5 = 500

Therefore, the value for common factors is 500.

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 = 172955550300000/(1x500)

LCM = 172955550300000/500

LCM = 345911100600

Thus, we can understand that the LCM of 645,806,515,950,680 is 345911100600.
