What is the smallest number that must be added to 7,795 so that the result is exactly divisible by 7?

💡 Solution & Explanation

Divide 7,795 by 7: the quotient is 1113 and the remainder is 4. To reach the next multiple of 7, add 7 − 4 = 3. Check: 7,795 + 3 = 7,798, which is 7 × 1114. Note that 4 is the number to subtract, not add, to get a multiple of 7.
