Hey mate this is your answer
Since 7 is a prime number, the only factors it has are the numbers 1 and 7. Multiples of 7are numbers that can be divided evenly by 7. If you count by 7, you are naming multiples. So, 7, 14, 21, 28, 35, 42, 49 and so on are all 'multiples' of 7.
So 81 is not a factor of 81
