How many integers between 1 and 200 are multiples of both 3 and 5 but not of either 4 or 7? How many integers between 504 and 1188 are multiples of 6? What is the number of integers from (999, 9999) that are divisible by 4 and are not divisible by 5?
CWrite out the product of five consecutive integers and call their product P . Then P=(n)(n+1)(n+2)(n+3)(n+4) . Note that exactly one of these numbers will be divisible by 5 , and at least one of these numbers will be divisible by 3 and 4. Either two or three of these ...
Solution. We would like to know if there are integers ro and yo so that ro is divisibleby 126, yo is divisible by 81, and xo + yo = 10000. Since ro is divisible by 126, we canwrite2o= 126xfor some intcger x. Likewise, we can write9o= 81y .for some integer y. Replacing ...
