Given numbers are 720,497,899,728

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

The LCM of 720,497,899,728 is 4182076080.

Find LCM of 720,497,899,728 with Prime Factorization

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

2 x 2 x 2 x 7 x 90 x 71 x 899 x 13 = 4182076080

Therefore, the lowest common multiple of 720,497,899,728 is 4182076080.

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.

720 x 497 x 899 x 728 = 234196260480

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.

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

497 : 1, 7, 71, 497

899 : 1, 29, 31, 899

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,497,899,728, is 1.

Now, the common factors can be found like this.

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

497:7x 71

899:29x 31

728:2x 2x 2x 7x 13

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 7 = 56

Therefore, the value for common factors is 56.

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 = 234196260480/(1x56)

LCM = 234196260480/56

LCM = 4182076080

Thus, we can understand that the LCM of 720,497,899,728 is 4182076080.
