Given numbers are 257,484,458,687

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

The LCM of 257,484,458,687 is 85454556.

Find LCM of 257,484,458,687 with Prime Factorization

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

2 x 229 x 257 x 242 x 1 x 3 = 85454556

Therefore, the lowest common multiple of 257,484,458,687 is 85454556.

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.

257 x 484 x 458 x 687 = 39138186648

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.

257 : 1, 257

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

458 : 1, 2, 229, 458

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,484,458,687, is 1.

Now, the common factors can be found like this.

257:257

484:2x 2x 11x 11

458:2x 229

687:3x 229

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

2x 229 = 458

Therefore, the value for common factors is 458.

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 = 39138186648/(1x458)

LCM = 39138186648/458

LCM = 85454556

Thus, we can understand that the LCM of 257,484,458,687 is 85454556.
