Given numbers are 261,997,997,997

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

The LCM of 261,997,997,997 is 260217.

Find LCM of 261,997,997,997 with Prime Factorization

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

997 x 261 x 1 x 1 x 1 = 260217

Therefore, the lowest common multiple of 261,997,997,997 is 260217.

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.

261 x 997 x 997 x 997 = 258658039953

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.

261 : 1, 3, 9, 29, 87, 261

997 : 1, 997

997 : 1, 997

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,997,997,997, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

997:997

997:997

997:997

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

997x 997 = 994009

Therefore, the value for common factors is 994009.

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 = 258658039953/(1x994009)

LCM = 258658039953/994009

LCM = 260217

Thus, we can understand that the LCM of 261,997,997,997 is 260217.
