Given numbers are 855,440,473,115

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

The LCM of 855,440,473,115 is 74412360.

Find LCM of 855,440,473,115 with Prime Factorization

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

5 x 11 x 171 x 8 x 43 x 23 = 74412360

Therefore, the lowest common multiple of 855,440,473,115 is 74412360.

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 440 x 473 x 115 = 20463399000

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

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

473 : 1, 11, 43, 473

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,440,473,115, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

440:2x 2x 2x 5x 11

473:11x 43

115:5x 23

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

5x 5x 11 = 275

Therefore, the value for common factors is 275.

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 = 20463399000/(1x275)

LCM = 20463399000/275

LCM = 74412360

Thus, we can understand that the LCM of 855,440,473,115 is 74412360.
