Given numbers are 902,195,860,805,855

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

The LCM of 902,195,860,805,855 is 138816257580.

Find LCM of 902,195,860,805,855 with Prime Factorization

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

2 x 3 x 5 x 451 x 13 x 86 x 161 x 57 = 138816257580

Therefore, the lowest common multiple of 902,195,860,805,855 is 138816257580.

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.

902 x 195 x 860 x 805 x 855 = 104112193185000

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.

902 : 1, 2, 11, 22, 41, 82, 451, 902

195 : 1, 3, 5, 13, 15, 39, 65, 195

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

805 : 1, 5, 7, 23, 35, 115, 161, 805

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,195,860,805,855, is 1.

Now, the common factors can be found like this.

902:2x 11x 41

195:3x 5x 13

860:2x 2x 5x 43

805:5x 7x 23

855:3x 3x 5x 19

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

2x 3x 5x 5x 5 = 750

Therefore, the value for common factors is 750.

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 = 104112193185000/(1x750)

LCM = 104112193185000/750

LCM = 138816257580

Thus, we can understand that the LCM of 902,195,860,805,855 is 138816257580.
