What is the total numbers of odd factors of 240?1. 102. 203. 44. 16

Answer» Correct Answer - Option 3 : 4

Given:

Number = 240

Formula used:

Number = ab × cd × ef

Then total number of factors = (b + 1)(d + 1)(f + 1)

If b is even then, the total number of odd factor = (d + 1)(f + 1)

Number of even factor = Total number of factors – Total number of odd factors

Calculations:

Factorization of 240 = 24 × 31 × 51

Here, 4 is even then,

Total number of odd factor = (1 + 1)(1 + 1) = 2 × 2 = 4

∴ The total number of odd factors of 240 is 4
