Given numbers are 720,914,305,554

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

The LCM of 720,914,305,554 is 5559788880.

Find LCM of 720,914,305,554 with Prime Factorization

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

2 x 5 x 72 x 457 x 61 x 277 = 5559788880

Therefore, the lowest common multiple of 720,914,305,554 is 5559788880.

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 914 x 305 x 554 = 111195777600

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

914 : 1, 2, 457, 914

305 : 1, 5, 61, 305

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,914,305,554, is 1.

Now, the common factors can be found like this.

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

914:2x 457

305:5x 61

554:2x 277

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 5 = 20

Therefore, the value for common factors is 20.

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 = 111195777600/(1x20)

LCM = 111195777600/20

LCM = 5559788880

Thus, we can understand that the LCM of 720,914,305,554 is 5559788880.
