There is no simple rule for finding out if a number if divisible by 13.The only method that I know is as follows:Split the number into two parts: the first part (A) comprises all but the last (units) digit, and the second part B is the units digit.Calculate A+4BRepeat with this new number until you reach 13, 26 or 39 (or 0 if you are looking for divisibility of 0!). AnySo, for example,1755 gives 175 + 4*5 = 175 + 20 = 195195 gives 19 + 4*5 = 19 + 20 = 39therefore 1755 is divisible by 13.

No, both 13 and 100 must be divisible by a common number, since 13 can only be divisible by itself and 1, it is considered a prime number. Ex of using a common number: 20/40 has both 10 and 20 in common, so it can be rewritten as 10/20 or 1/2
Yes, if a number is divisible by 20, then it is also an even number. This is because any number that is divisible by 20 must also be divisible by 2, as 20 is a multiple of 2. Since even numbers are multiples of 2, any number divisible by 20 will be a multiple of 2 and therefore even.
No. The smallest number divisible by both 5 and 2 is their lowest common Multiple (LCM) which is 10; ALL multiples of their LCM are divisible by 5 and 2, ie 10, 20, 30, 40, 50, ... are all divisible by 5 and 2.
A prime number is a number that is only divisible by itself, and 1. The largest prime number below 20 is 19. The smallest prime number above 60 is 61. So the answer will be 19 + 61 = 80
