the number 878800000 can be written as 2^7 *5^5 *13^3
so, for odd factors, we need only ( 5^5 * 13 ^3)
total odd factor=(5+1)*(3+1)=24 (option 10 none of these)

878800000 = 2^7 * 5 ^5 * 13^3. As odd numbers do not have 2 as a factor, total odd numbers can be calculated with considering 5 6 times and 13 4 times. hence 6*4 = 24
