Given numbers are 290,731,731,987

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

The LCM of 290,731,731,987 is 209234130.

Find LCM of 290,731,731,987 with Prime Factorization

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

17 x 43 x 290 x 1 x 1 x 987 = 209234130

Therefore, the lowest common multiple of 290,731,731,987 is 209234130.

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.

290 x 731 x 731 x 987 = 152950149030

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.

290 : 1, 2, 5, 10, 29, 58, 145, 290

731 : 1, 17, 43, 731

731 : 1, 17, 43, 731

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,731,731,987, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

731:17x 43

731:17x 43

987:3x 7x 47

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

17x 43 = 731

Therefore, the value for common factors is 731.

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 = 152950149030/(1x731)

LCM = 152950149030/731

LCM = 209234130

Thus, we can understand that the LCM of 290,731,731,987 is 209234130.
