Definitely COMPOSITE.
Remember ALL EVEN number end in (0,2,4,6,8) are Composite, because '2' is a factor of all EVEN numbers, thereby making them Composite/Compound.
NB Odd Number, ending in (1,3,5,7,9) can be either Composite or Prime, but NOT both.
Since '90' end in '0' then it is EVEN. It will divide by '2' , making it composite.
90/2 = 45
How about 74 and 76
A number is composite if it has factors apart from 1 and the number itself. Otherwise it is prime. All even numbers (except 2) are composite.
