How many of the positive divisors F of 120 are also multiples of 4 not including 120? Select.
A) 3. B) 4. C) 5. D) 7. E) 8.
4,8,12,20,24,40,60. (7) is the answer   Other way : factors of 120 = 2^3 * 3*5   Separate 2^2 ( which means 4)   Now, calculate the number of other factors.   F=2*3*5 = total positive factors are 2*2*2=
