IT CAN ALSO EVEN DIVIDED IN TWO DIVISORS WHICH IS 1 AND IT-SELF.
EXAMPLE, 17 SO THEREFORE 17 IS A PRIME NUMBER BECAUSE IT HAS ONLY 2 FACTORS AND IT-SELF.

COMPOSITE NUMBERS

COMPOSITE NUMBERS ARE WHOLE NUMBERS GREATER THAN 1 THAT HAS MORE THAN 2 FACTORS.
EXAMPLE, 1×15 = 15, 3×5 = 15 SO THEREFORE 15 IS A COMPOSITE NUMBER BECAUSE IT HAS MORE THAN 2 FACTORS AND IT-SELF.
