Given numbers are 391,313,687,458

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

The LCM of 391,313,687,458 is 168154242.

Find LCM of 391,313,687,458 with Prime Factorization

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

229 x 391 x 313 x 3 x 2 = 168154242

Therefore, the lowest common multiple of 391,313,687,458 is 168154242.

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.

391 x 313 x 687 x 458 = 38507321418

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.

391 : 1, 17, 23, 391

313 : 1, 313

687 : 1, 3, 229, 687

458 : 1, 2, 229, 458

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,313,687,458, is 1.

Now, the common factors can be found like this.

391:17x 23

313:313

687:3x 229

458:2x 229

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

229 = 229

Therefore, the value for common factors is 229.

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 = 38507321418/(1x229)

LCM = 38507321418/229

LCM = 168154242

Thus, we can understand that the LCM of 391,313,687,458 is 168154242.
