so exg
prime factorization is finding the prime number that will multiply to getthat tnumber
normally we exclude the number 1
so prime factor of 6=2 times 3
note:2*3 menas 2 times 3
so 891
it is odd so not divisible by 2
try 3
891/3=297
3*297=891
factor further
297
try 3
297/3=99
3*3*99=891
99
divide by 3
33
3*3*3*33
33
divide by 3
11
3*3*3*3*11
11 is prime so the prime factoization is
3*3*3*3*11 or 3^4*11
