It is divisible by 10, and the tens digit is even. 360: is divisible by 10, and 6 is even. The last two digits are 00, 20, 40, 60 or 80. [3] 480: 80 It is divisible by 4 and by 5. 480: it is divisible by 4 and by 5. 21: Subtracting twice the last digit from the rest gives a multiple of 21.
d() is the number of positive divisors of n, including 1 and n itself; σ() is the sum of the positive divisors of n, including 1 and n itselfs() is the sum of the proper divisors of n, including 1 but not n itself; that is, s(n) = σ(n) − n
