A number that is divisible by both 31 and 24 must be a multiple of their least common multiple (LCM), which is 744. Therefore, any number that is a multiple of 744 will be divisible by both 31 and 24. This means that numbers like 744, 1488, 2232, and so on will satisfy the criteria of being divisible by both 31 and 24.
