8 3/7-2 1/2
= 59/7 - 5/2
= 118/14 - 35/14
= 83/14 or 5 13/14
93 = 3x31
524 = 2x2x131
both 31 and 131 are primes

I said 425 or IS that how d]you do it
With what Reiny showed, there should be sufficient information to work out 425 by yourself as an exercise.
I will give you another example, 525:
525÷5=105
105÷5=21
21÷3=7
since 7 is a prime we cannot go further.
so
525=5*5*3*7=3*5²*7
You're welcome to post your answer for 425 for checking if you wish.
