The number of odd divisors of 128
WebDec 29, 2011 · Actually the divisors are doubled up when the number is not a square. Take 12. The groups are {1,12}, {2,6} and {3,4}. Since the divisors are all in groups of 2, the number of divisors is even. Now take 64, a perfect square. The groups are {1,64}, {2,32}, {4,16} and {8}. 8*8=64 so 8 is in a group all by itself. Hence the number of divisors is odd. WebThe tables below list all of the divisorsof the numbers 1 to 1000. A divisorof an integernis an integer m, for which n/mis again an integer (which is necessarily also a divisor of n). For example, 3 is a divisor of 21, since 21/7 = 3 (and therefore 7 is also a divisor of 21). If mis a divisor of nthen so is −m.
