Answer:
600
Step-by-step explanation:
The prime factors of the numbers given are 2*2*5, 5*5, 3*2*5, and 2*2*2*5. So a multiple needs to 2*2*2*3*5*5, or 600. But “smallest” can be negative. There is no smallest such number, as for any candidate X you can always subtract 600 to get X-600 which also qualifies.
