Find the sum of the factors of 360.
Explanation:
For a number n = ax × by × cz
Sum of factors = (ax + ax-1 + ... + 1)(by + by-1 + ... + 1)(cz + cz-1 + ... + 1)
360 = 23 × 32 × 5
Sum of factors of 360 = (23 + 22 + 21 + 1)(32 + 31 + 1)(51 + 1)
∴ The sum of the factors of 360 = 23+1-132+1-1)(5(1+1)-1)2-1(3-1)(5-1) = 1170
Hence, 1170.
