(a) A divisibility test for divisibility by 29 is to subtract 26 times the last digit from the other digits; if the result is a number divisible by 29, then the original number is divisible by 29. For example, 261 is divisible by 29 because 26 - 26-1 = 0 is divisible by 29. Find a related but easier test for divisibility by 23. (b) Describe (in complete sentence(s) a divisibility test for the number 174.
