jika diketahui himpunan s={faktor dari 70},maka tentukan himpunan himpunan bagian dari s!

s = {1,2,5,7,10,14,35,70}

himpunan bagian :
{ }
{1} , {2} , {5} , {7} , {10} , {14} , {35} , {70}
{1,2} , {1,5} , {1,7} , {1,10} , {1,14}, {1,35}, {1,70} , {2,5} , {2,7} , {2,10} , {2,14} , {2,35} , {2,70} , {5,7} , {5,10} , dst
{1,2,5} , {1,2,7} , {1,2,10} , {1,2,14} , {1,2,35} , {1,2,70} , {1,5,7} , {1,5,10} , {1,5,14} , {1,5,35} , {1,5,70} , {1,7,10} , {1,7,14} , {1,7,35} , {1,7,70} , {1,10,14} , {1,10,35} , {1,10,70} , {1,14,35} , dst
