We can find the prime factorization of each number:
$24=2^3\cdot3$
$90=2\cdot3^2\cdot5$
To find the least common multiple, we take the highest power of each prime that appears in either factorization:
$2^3\cdot3^2\cdot5=8\cdot9\cdot5=360$
So the least common multiple of 24 and 90 is $\boxed{360}$.
The answer is: 360
