Given numbers are 520,629,729,689,720

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

The LCM of 520,629,729,689,720 is 25274779920.

Find LCM of 520,629,729,689,720 with Prime Factorization

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

2 x 2 x 2 x 3 x 3 x 5 x 13 x 1 x 629 x 81 x 53 x 2 = 25274779920

Therefore, the lowest common multiple of 520,629,729,689,720 is 25274779920.

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.

520 x 629 x 729 x 689 x 720 = 118285970025600

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

629 : 1, 17, 37, 629

729 : 1, 3, 9, 27, 81, 243, 729

689 : 1, 13, 53, 689

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,629,729,689,720, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

629:17x 37

729:3x 3x 3x 3x 3x 3

689:13x 53

720:2x 2x 2x 2x 3x 3x 5

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 13 = 4680

Therefore, the value for common factors is 4680.

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 = 118285970025600/(1x4680)

LCM = 118285970025600/4680

LCM = 25274779920

Thus, we can understand that the LCM of 520,629,729,689,720 is 25274779920.
