Find the sum of the factors of 3240.

Question: Find the sum of the factors of 3240.Solution:If k = ax × by, then a, and b must be prime numberSum of all factors = (a0 + a1 + a2 + ….. + ax) (b0 + b1 + b2 + ….. + by) 3240 = 23 × 34 × 51 Sum of factors = (20 + 21 + 22 + 23) (30 + 31 + 32 + 33 + 34) (50 + 51) = (1 + 2 + 4 + 8) (1 + 3 + 9 + 27 + 81) (1 + 5) = 15 × 121 × 6 = 10890 ∴ required sum is 10890
