Note: The answers to the above problems are all in the back of the text except for #21, 22, and 27. Answers below:
21. Any number of the form p5-1=p4, where p is a prime. For example, 32, 81, 256, ...
22.Since 144=12*12=(3*4)(3*4)=32*24, it has 3*5=15 divisors.
27.If the GCD is 1 the numbers have no divisors in common so their LCM is the product of the numbers. Since GCD(a,b)*LCM(a,b) = a*b, and GCD(a,b)=1, LCM(a,b) = a*b. |
