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.
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
prim
98 is an even number. The only even prime is 2, so 98 is not prime. Therefore it is composite. That's one logic method. Another would be to show the factors (other than 1 and 98) such as (49 x 2) or (7 x 14). Since it as factors other than 1 and itself, then it is composite.
