Given numbers are 855,303,573,312,721

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

The LCM of 855,303,573,312,721 is 1236771474120.

Find LCM of 855,303,573,312,721 with Prime Factorization

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

3 x 285 x 101 x 191 x 104 x 721 = 1236771474120

Therefore, the lowest common multiple of 855,303,573,312,721 is 1236771474120.

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.

855 x 303 x 573 x 312 x 721 = 33392829801240

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

303 : 1, 3, 101, 303

573 : 1, 3, 191, 573

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,303,573,312,721, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

303:3x 101

573:3x 191

312:2x 2x 2x 3x 13

721:7x 103

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 33392829801240/(1x27)

LCM = 33392829801240/27

LCM = 1236771474120

Thus, we can understand that the LCM of 855,303,573,312,721 is 1236771474120.
