Best ResponseYou've already chosen the best response.3the first divisor is 2: 240/2=120 120/2=60 60/2=30 30/2=15 15/3=5 5/5=1 each time you divide new number by the it's smallest divisor: thus your divisors are 2, 4, 8, 16, 6, 10, 48, 30, 15, 60, 5, 120, 240, 1, 3, 80 , 24, 12, 20, 40, that's all if i didn't forgot anything prime factorization is 2*2*2*2*3*5

Best ResponseYou've already chosen the best response.3\(240 = 2^4*3*5\) So, any divisor of \(240\) will be of form \(2^a*3^b*5^c\), where \(0\le a\le 4\) and \(~0\le b,c\le 1\)

Best ResponseYou've already chosen the best response.3Notice that we can choose the exponent \(a\) in \(5\) ways, \(b\) in \(2\) ways, \(c\) in \(2\) ways therefore total number of positive divisors = \(5*2*2=20\)

Best ResponseYou've already chosen the best response.2i just remembered the pattern (a+1)(b+1)(c+1)....=no of divisors
