Given numbers are 990,860,731,977,194

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

The LCM of 990,860,731,977,194 is 137166755220.

Find LCM of 990,860,731,977,194 with Prime Factorization

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

2 x 5 x 43 x 99 x 2 x 17 x 977 x 97 = 137166755220

Therefore, the lowest common multiple of 990,860,731,977,194 is 137166755220.

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.

990 x 860 x 731 x 977 x 194 = 117963409489200

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.

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

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

731 : 1, 17, 43, 731

977 : 1, 977

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,860,731,977,194, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

860:2x 2x 5x 43

731:17x 43

977:977

194:2x 97

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 5x 43 = 860

Therefore, the value for common factors is 860.

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 = 117963409489200/(1x860)

LCM = 117963409489200/860

LCM = 137166755220

Thus, we can understand that the LCM of 990,860,731,977,194 is 137166755220.
