Given numbers are 190,301,731,989

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

The LCM of 190,301,731,989 is 22361290.

Find LCM of 190,301,731,989 with Prime Factorization

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

43 x 190 x 7 x 17 x 23 = 22361290

Therefore, the lowest common multiple of 190,301,731,989 is 22361290.

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.

190 x 301 x 731 x 989 = 41346025210

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.

190 : 1, 2, 5, 10, 19, 38, 95, 190

301 : 1, 7, 43, 301

731 : 1, 17, 43, 731

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,301,731,989, is 1.

Now, the common factors can be found like this.

190:2x 5x 19

301:7x 43

731:17x 43

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.

43x 43 = 1849

Therefore, the value for common factors is 1849.

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 = 41346025210/(1x1849)

LCM = 41346025210/1849

LCM = 22361290

Thus, we can understand that the LCM of 190,301,731,989 is 22361290.
