Given numbers are 215,285,257,572

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

The LCM of 215,285,257,572 is 1801534020.

Find LCM of 215,285,257,572 with Prime Factorization

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

5 x 43 x 57 x 257 x 572 = 1801534020

Therefore, the lowest common multiple of 215,285,257,572 is 1801534020.

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.

215 x 285 x 257 x 572 = 9007670100

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.

215 : 1, 5, 43, 215

285 : 1, 3, 5, 15, 19, 57, 95, 285

257 : 1, 257

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,285,257,572, is 1.

Now, the common factors can be found like this.

215:5x 43

285:3x 5x 19

257:257

572:2x 2x 11x 13

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

5 = 5

Therefore, the value for common factors is 5.

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 = 9007670100/(1x5)

LCM = 9007670100/5

LCM = 1801534020

Thus, we can understand that the LCM of 215,285,257,572 is 1801534020.
