Answer 1

95 ends in a 5 so we should know that it is divisible by 5 at least:

5 * 19 ; and i think that 5 and 19 are primes

Answer 2

s imple strategy is; if its even, divide in half; if odd, start seeing which odds divide it

Answer 3

if number is even keep dividing by 2 until u get odd number then try 3 , 5 ....
