Given numbers are 257,312,258,419,515

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

The LCM of 257,312,258,419,515 is 744007690920.

Find LCM of 257,312,258,419,515 with Prime Factorization

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

2 x 3 x 257 x 52 x 43 x 419 x 515 = 744007690920

Therefore, the lowest common multiple of 257,312,258,419,515 is 744007690920.

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 312 x 258 x 419 x 515 = 4464046145520

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

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

258 : 1, 2, 3, 6, 43, 86, 129, 258

419 : 1, 419

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,312,258,419,515, is 1.

Now, the common factors can be found like this.

257:257

312:2x 2x 2x 3x 13

258:2x 3x 43

419:419

515:5x 103

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 4464046145520/(1x6)

LCM = 4464046145520/6

LCM = 744007690920

Thus, we can understand that the LCM of 257,312,258,419,515 is 744007690920.
