How many positive integers less than 5,000 are evenly divisible by neither 15 nor 22? | deepmind/aqua_rat | [
"4,514",
"4,475",
"4,521",
"4,428"
] | A | integers less than 5000 divisible by 15 5000/15 =333.something , so 333
integers less than 5000 divisible by 22 5000/22 = 238.## , so 238
we have double counted some, so take LCM of 15 and 22 =105 and divide by 5000, we get 47. so all numbers divisible by 15 and 22 = 333 +238 -47 =524
now subtract that from 4999. 4999-... |
