The required number must meet three criteria: be less than 40, have 7 as a factor, and have a digit sum of 8. The multiples of 7 under 40 are 7, 14, 21, 28, and 35. Out of these, only 35 satisfies the digit sum condition (3 + 5 = 8). Its complete set of factors is 1, 5, 7, and 35. Thus, the answer iRead more

To solve, the number must be under 100, divisible by both 3 and 5, and its digits differ by 1. Numbers divisible by 3 and 5 have 15 as their least common multiple. Checking these, 15 fits perfectly, as its digits (1 and 5) meet the condition where one is exactly 1 more than the other. The factors ofRead more
