First, we will divide 1056 by 23. Required number = 23 − 21 = 2So, 2 must be added to 1056 to make it exactly divisible by 23.i.e., 1056 + 2 = 1058 Now, we have: ∴ 1058 is exactly divisible by 23. Concept: Concept for Whole Numbers Is there an error in this question or solution? Page 3We have to find the largest four digit number divisible by 16 .The largest four-digit number = 9999Therefore, dividend =9999 Divisor =16 Here, we get remainder =15Therefore, 15 must be subtracted from 9999 to get the largest four digit number that is divisible by 16.i.e., 9999 − 15 = 9984 Thus, 9984 is the largest four-digit number that is divisible by 16. |
