What are the greatest and least numbers between 900 and 1000 that are divisible by 10 5 and 2?

To find the greatest number between 900 and 1000 that is divisible by 10, 5, and 2, we need to find the least common multiple (LCM) of 10, 5, and 2, which is 10. So, we look for the highest multiple of 10 between 900 and 1000, which is 990. To find the least number between 900 and 1000 that is divisible by 10, 5, and 2, we can simply find the smallest multiple of 10 in that range, which is 900.
