Problems within the power steering unit cause even louder noises, but they often do not happen until you turn the wheel as far as you can in one direction. If the power steering drive belt is loose or damaged, whining often gets quite loud.
The number 2 57,885,161 â 1 has picked up the baton as the largest known prime number, a result that is tremendously exciting for mathematicians, if rather irrelevant to the rest of mathematics. Primes are numbers that can only be divided by themselves and 1, such as 2, 3, 5, 7 and 11.
A prime number is a number whose only proper divisor is 1. Thus a prime number can be composed only of 1's. 17 and 29 are prime numbers. Again, 1 is a proper divisor of every number (except itself), but a prime number has 1 as its only proper divisor.
