THE FACTORS OF 18 ARE 1,2,3,6,9 AND 18.
these five numbers are divisible by 18 . so these five numbers are the factors of 18.
explanation:
18 can be written as the multiples of
i) 9x2
ii) 1x18 and
iii) 6x3
these three options are the only multiples of 18.
now its clear that the factors of a number is obviously the divisors of that number
