分析:先找出1008的所有因數(shù)有1008的所有因數(shù)是1,1008,2,504,3,336,4,252,6,168,7,144,8,126,9,112,12,84,14,72,16,63,18,56,21,48,24,42,28,36.然后把它們相加即可.
解答:解:1008的所有因數(shù)是1,1008,2,504,3,336,4,252,6,168,7,144,8,126,9,112,12,84,14,72,16,63,18,56,21,48,24,42,28,36.
1+1008+2+504+3+336+4+252+6+168+7+144+8+126+9+112+12+84+14+72+16+63+18+56+21+48+24+42+28+36=3224.
故答案為:3224.
點評:此類題做題的關(guān)鍵是先找出28的約數(shù),然后根據(jù)題意,相加即可得出結(jié)論.
