Given numbers are 261,174,419,447,289

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

The LCM of 261,174,419,447,289 is 9418215798.

Find LCM of 261,174,419,447,289 with Prime Factorization

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

3 x 29 x 3 x 2 x 419 x 149 x 289 = 9418215798

Therefore, the lowest common multiple of 261,174,419,447,289 is 9418215798.

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 174 x 419 x 447 x 289 = 2458154323278

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

174 : 1, 2, 3, 6, 29, 58, 87, 174

419 : 1, 419

447 : 1, 3, 149, 447

289 : 1, 17, 289

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,174,419,447,289, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

174:2x 3x 29

419:419

447:3x 149

289:17x 17

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

3x 3x 29 = 261

Therefore, the value for common factors is 261.

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 = 2458154323278/(1x261)

LCM = 2458154323278/261

LCM = 9418215798

Thus, we can understand that the LCM of 261,174,419,447,289 is 9418215798.
