Given numbers are 855,530,682,120,989

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

The LCM of 855,530,682,120,989 is 122259507480.

Find LCM of 855,530,682,120,989 with Prime Factorization

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

2 x 3 x 5 x 57 x 53 x 341 x 4 x 989 = 122259507480

Therefore, the lowest common multiple of 855,530,682,120,989 is 122259507480.

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 530 x 682 x 120 x 989 = 36677852244000

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

530 : 1, 2, 5, 10, 53, 106, 265, 530

682 : 1, 2, 11, 22, 31, 62, 341, 682

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,530,682,120,989, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

530:2x 5x 53

682:2x 11x 31

120:2x 2x 2x 3x 5

989:23x 43

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 3x 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 36677852244000/(1x300)

LCM = 36677852244000/300

LCM = 122259507480

Thus, we can understand that the LCM of 855,530,682,120,989 is 122259507480.
